The fixed 3.3 V output eliminates resistor-divider design effort, while the 1 MHz switching frequency keeps the fundamental ripple well above the AM band and enables a small 1 µH-class inductor. When designing with the TS30011-M033QFNR, use a 22 µF X5R/X7R ceramic input capacitor and a 22 µF ceramic output capacitor placed within 5 mm of the IC, plus a 1 µH to 4.7 µH shielded inductor rated for at least 1.5 A saturation current. Place the exposed pad on a continuous ground copper pour of at least 1 square inch to keep junction temperature within derating limits.

TS30011-M050QFNR - 1A 5V Sync Buck DC/DC | Semtech | QFN-16
The Semtech TS30011-M050QFNR is a 1 A high-efficiency synchronous buck DC/DC switching regulator with a fixed 5 V output, housed in a 16-pin QFN exposed-pad (3x3 mm) package. It operates from a 4.5 V to 24 V input range, switches at 1 MHz, and integrates both high-side and low-side MOSFETs along with internal compensation and full fault protection including input under-voltage lockout, output soft start, cycle-by-cycle current limit, and thermal shutdown. A buck (step-down) DC/DC converter is a switch-mode power supply topology that rapidly switches an input voltage across an inductor to produce a lower, regulated output voltage. Compared with linear regulators, buck converters achieve much higher efficiency (typically >90%) at large VIN-VOUT differentials because they recycle energy through the inductor rather than dissipating it as heat. The TS30011 family (TS30011/12/13) spans 1 A/2 A/3 A current ratings, positioning it for compact, thermally-constrained distributed power architectures. Key specifications include a fixed 5 V output, 1 A continuous load current, 1 MHz switching frequency (enabling small ceramic output capacitors), and 4.5 V to 24 V input range. The fully integrated power switches eliminate the need for external MOSFETs, while internal compensation removes the external RC network required by many controllers. A Power Good (PG) open-drain output provides supervisory reporting to downstream system components for sequencing and fault handling. Architecturally, the device uses a peak-current-mode control loop that provides cycle-by-cycle current limiting and simplifies frequency compensation. Synchronous rectification (replacing the external Schottky with an internal low-side FET) reduces conduction loss and improves light-load efficiency, while the high 1 MHz switching frequency shrinks the external LC filter to a few small ceramic capacitors, keeping the total solution footprint under 50 mm^2. Typical applications include 24 V industrial bus point-of-load regulation, USB-powered 5 V rails, set-top box and home gateway supply rails, and distributed 5 V power in FPGA/CPLD-based systems. The wide 4.5 V-24 V input range supports direct connection to 12 V or 24 V industrial backplanes. When designing with this device, note that the fixed 5 V output cannot be adjusted. Designers needing 3.3 V, 2.5 V, 1.8 V, or adjustable rails should select the TS30011-M033QFNR, -M025QFNR, -M018QFNR, or -M000QFNR variants instead. The exposed pad must be soldered to a thermal copper pour to keep junction temperature within ratings at full load. This page synthesizes verified distributor pricing from DigiKey, Mouser, Arrow, LCSC and Newark, cross-references drop-in package-compatible alternatives from the TS30011/12/13 family and competing 1 A synchronous buck converters, and adds practical design notes beyond what is found in the manufacturer datasheet alone.
TS30011-MC00QFNR - 1A Sync Buck DC/DC Converter, 4.5-24V | Semtech
The Semtech TS30011-MC00QFNR is a 1A high-efficiency synchronous buck DC/DC switching regulator integrated in a 16-pin VFQFN exposed pad (QFNR) package, with an adjustable output variant from the TS30011 family. The device accepts a 4.5V to 24V input supply and operates at a fixed 1 MHz switching frequency, integrating both high-side and low-side MOSFET switches, internal compensation, and full protection (UVLO, soft-start, current limit, thermal shutdown) on-chip. A synchronous buck converter (also called synchronous step-down or synchronous switching regulator) is a DC/DC topology that uses two MOSFETs to convert a higher DC input voltage into a lower DC output voltage with high efficiency. It belongs to the hierarchy: DC/DC switching regulator -> buck converter -> switching regulator -> voltage regulator -> power management IC. The synchronous architecture replaces the conventional Schottky diode with a low-side MOSFET, dramatically reducing conduction losses at heavy loads and pushing typical efficiency above 90 percent - compared to ~70-80 percent for asynchronous buck converters. Key specifications include 1 MHz PWM switching (enabling small L/C filter components and low EMI), 1A continuous output current, integrated 130 mOhm high-side and 70 mOhm low-side MOSFETs (typical), 4.5V to 24V input range, and a Power Good (PG) open-drain output for system-level sequencing. The exposed-pad package keeps junction-to-ambient thermal resistance low for 1A applications without an external heatsink. The TS30011 uses peak current-mode control with internal slope compensation to simplify loop compensation. The 1 MHz switching frequency is intentionally placed outside the AM broadcast band to ease EMI compliance for consumer audio and industrial applications. Soft-start, input under-voltage lockout, cycle-by-cycle current limiting, and thermal shutdown are all integrated as protection functions, and the PG output flags when VOUT is within regulation for multi-rail processors. Typical applications include point-of-load (POL) converters for 12V-distributed industrial systems, USB-C powered device downstream rails, solid-state drive (SSD) and 5V auxiliary rails, FPGA/CPLD core and I/O supplies, and 24V-to-5V/3.3V intermediate bus converters in factory automation. When designing with this part, choose an external inductor in the 2.2 uH to 4.7 uH range, place the input and output ceramic bypass capacitors (typically 10 uF X7R) within 2 mm of the IC pins, and connect the exposed pad to a copper pour of at least 0.5 square inches to achieve the datasheet thermal ratings.
TUHS3F12 - 3W 12V 250mA PCB Mount AC-DC Converter | Cosel
The Cosel TUHS3F12 is a 3 W PCB-mount enclosed AC-DC converter module delivering a single regulated 12 V output at 250 mA, with a universal input range of 85 to 264 VAC (50/60 Hz) or 120 to 370 VDC. The module belongs to Cosel's TUHS series of compact board-mount power supplies designed for direct installation onto a printed circuit board without an external enclosure. An AC-DC converter (also called an off-line power supply module) converts mains alternating current into a low-voltage regulated direct-current output. Within the power-management hierarchy, it sits above DC-DC converters, which only convert an already-rectified DC rail; an AC-DC module handles rectification, power-factor correction, isolation, regulation, and protection in a single encapsulated package. Key features of the TUHS3F12 include built-in overcurrent and overvoltage protection circuits, a small footprint that greatly reduces board area, and design flexibility for hold-up time and expected life. Cosel's series documentation highlights low-noise technology and soft switching circuits that achieve high efficiency and low standby power across the TUHS range (3 W to 30 W). Notably, the module is not built with aluminum or tantalum electrolytic capacitors, which improves long-term reliability and extends expected service life compared with conventional designs. Technically, the TUHS3F12 is a member of the 3 W tier of the TUHS family; larger family members such as the TUHS25 employ synchronous rectification for further efficiency gains. The universal input permits direct connection to worldwide single-phase mains without jumper selection, making the module suitable for globally deployed equipment. The encapsulated through-hole construction provides resistance to dust, moisture, and vibration. Typical applications include industrial control equipment, household appliances, network and communication devices, LED lighting drivers, and instrumentation where a compact, isolated low-power auxiliary supply is required directly on the main PCB. A key design consideration is thermal derating: at 3 W output the module must be mounted with adequate airflow and spacing to keep case temperature within the datasheet limit, and output current should not exceed 250 mA continuously. Hold-up time can be extended with an external output capacitor per Cosel's application guidance.

The output stage delivers ±1.5 A peak totem-pole drive, fully latched logic prevents multiple output pulses, and an internal 5.1V reference powers the control loop. Architecturally, the UC2825 uses a bipolar process with a double-ended push-pull output stage. The high peak drive current and 30V rating allow direct gate drive of power MOSFETs or small IGBTs in high-frequency SMPS designs. The fully-latched comparator logic eliminates jitter and double-pulsing that can occur in edge-triggered designs, producing clean gate waveforms at high frequency. Typical applications include telecom and server DC-DC converters, isolated bus converters using push-pull or bridge topologies, industrial power supplies, motor drivers, and high-frequency SMPS modules. The wide input range and high peak drive current make it well suited to 48V telecom rails, industrial 24V systems, and automotive-grade variants exist as UC2825-Q1. When designing with this device, choose external R/C timing values for the oscillator to set frequency and maximum duty cycle. Use Kelvin connections to the current-sense resistor for accurate 1V-threshold current limiting, and place bypass capacitors close to VCC and the 5.1V reference pin to maintain stability.

Its double-ended output configuration makes it ideal for push-pull and full-bridge topologies where two interleaved drive signals are required. When designing with the UC3824, careful attention must be paid to grounding and bypassing, as the high-speed switching can introduce noise. A ground plane is highly recommended, and the timing components should be placed close to the IC to minimize parasitic inductance.
