TS30011-MC00QFNR Übersicht
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.

Typische Anwendungen
TS30011-MC00QFNR ist geeignet für 6 Anwendungs: 12V Industrial POL Converter, SSD and Memory Subsystem Power, USB-C Powered Device Downstream Rail, FPGA and CPLD Core/I/O Supply, 24V Industrial Sensor / Actuator Rail, Battery-Powered Portable Equipment.
12V Industrial POL Converter
The TS30011-MC00QFNR's 4.5-24V input range and 1A/1 MHz synchronous buck topology make it ideal for point-of-load conversion from 12V or 24V industrial bus rails to 3.3V/5V/1.8V logic. Its peak current-mode control provides fast transient response to sudden loads from microcontrollers or sensors. The integrated high-side/low-side MOSFETs avoid external FET selection, while the PG flag and EN pin enable multi-rail sequencing for DSP and FPGA cores. Up to 93% efficiency at typical industrial duty ratios reduces thermal stress in fanless factory-automation enclosures.
Empfohlen
SSD and Memory Subsystem Power
Solid-state drives and DDR memory modules require tight, low-noise 1.0V to 3.3V rails at high current transients, a use case where the TS30011-MC00QFNR fits well. The 1 MHz switching frequency uses small 2.2 uH to 4.7 uH inductors, allowing a footprint of roughly 50 mm squared for the complete power stage. Synchronous rectification with 70 mOhm low-side RDS(on) keeps synchronous-rectification losses low at 1A loads, while the exposed pad package supports up to 1.5 W of dissipation without an external heatsink for typical SSD duty cycles.
Empfohlen
USB-C Powered Device Downstream Rail
USB-C Power Delivery (PD) contracts at 5V, 9V, 15V, or 20V place a downstream regulator after the PD controller; the TS30011-MC00QFNR with its 4.5-24V input spans all of those contracts. With a fixed 1 MHz switching frequency that lives above the AM broadcast band, the part eases EMI compliance for consumer audio/video accessories that might otherwise pick up switcher noise. Up to 93% efficiency at 5V to 3.3V conversion keeps the device class-compliant with USB-C thermal limits for hubs, docks, and powered monitors.
Empfohlen
FPGA and CPLD Core/I/O Supply
Modern FPGAs and CPLDs require multiple low-voltage, high-current rails (typically 1.0V-1.8V core and 2.5V-3.3V I/O), and the TS30011-MC00QFNR supplies these from a single 12V brick. The internal soft-start (programmable via SS/COMP cap) lets designers tune monotonic rail rise times, critical for SRAM-based FPGAs that need clean inrush. The PG open-drain output sequences the next rail in the stack, and the exposed-pad QFNR package keeps theta_JA low so 1A continuous load can be delivered without external cooling.
Empfohlen
24V Industrial Sensor / Actuator Rail
Factory sensors and small actuators commonly operate from 24V, requiring local DC/DC conversion to 5V or 3.3V for MCU and analog sensor signal chains. The TS30011-MC00QFNR's 24V-tolerant input range covers 24V with margin, and its 1A output handles multiple sensor loads in parallel. Cycle-by-cycle current limit and internal thermal shutdown protect against field wiring short circuits common in industrial installations, making it a robust alternative to discrete buck designs with extra protection.
Empfohlen
Battery-Powered Portable Equipment
Portable and battery-powered devices running from 1S-3S Li-ion stacks (3.0-12.6V) benefit from the TS30011-MC00QFNR's wide 4.5-24V input and 93% peak efficiency. Synchronous buck topology avoids the Schottky diode loss of asynchronous designs, critical for maximizing run-time in battery-operated instruments and wearables. The 1 MHz FSW allows a small 2.2 uH inductor and sub-5 mm profile PCB, which fits handheld enclosures and the strict form-factor constraints of portable products.

Wichtigste Unterscheidungsmerkmale
- Adjustable output vs family members (vs. TS30011-M033QFNR)
- High-side / low-side MOSFETs integrated (vs. TS30011-M033QFNR (same die))

Designhinweise
Place the input capacitor (10 uF X7R 25V or higher) within 2 mm of the VIN pins and bond both VIN pads together with a wide copper pour. The exposed pad must be soldered to a copper pour of at least 0.5 square inches (300 mm2) on the top or bottom PCB layer to achieve the datasheet theta_JA. Use multiple thermal vias under the exposed pad to the inner/ground layers. Keep the SW node trace short and away from FB/AGND to avoid capacitive noise injection into the feedback path.
Estimated: at VIN=12V, VOUT=5V, and IOUT=1A, the TS30011 dissipates roughly P = (VIN-VOUT) x IOUT + switching losses ~ 7 W. The 16-VFQFN package on a properly designed copper pour typically achieves theta_JA in the 30-40 C/W range; therefore junction temperature rise above ambient is around 25-30 C, leaving reasonable headroom below the 125 C thermal-shutdown threshold. For sustained operation at VIN=24V near full load, verify Tj by measurement or derate IOUT to keep Tj within ~115 C for long life.
Do not omit the bootstrap capacitor (C_BST, typically 100 nF) between BST and SW pins - without it the high-side MOSFET will not turn on and VOUT will be missing. Do not float the EN pin; tie it to VIN through a 100 kOhm resistor if unused. Connect PGND and AGND at a single star point near the exposed pad. Avoid using the SS/COMP node for any DC load - it is a high-impedance control node. Confirm the absolute maximum ratings from the Semtech datasheet before paralleling multiple TS30011 devices for higher current.
Keep the input capacitor return path and the SW loop area as small as possible - this minimizes EMI and switching noise. Place the output capacitor (typically 22 uF X7R) close to the inductor and feedback sense point to avoid high-frequency ringing on the SW node. Route the FB trace away from the SW trace and bridge using a Kelvin connection at the output capacitor. If the application is noise-sensitive (RF, audio), add a small 100 nF bypass cap on VOUT right at the load to filter the high-frequency ripple content above 10 MHz.
