PTH04T241W Overview
A non-isolated power module is a complete DC-DC converter that integrates the PWM controller, power MOSFETs, inductor, and compensation network into a single surface-mount package, delivering a regulated output without galvanic isolation. Such modules sit within the voltage regulator hierarchy, specifically the buck (step-down) DC-DC converter family of power management ICs, and dramatically reduce design time versus discrete converter implementations.
Key features include up to 96% efficiency, a total output voltage variation of only plus/minus 1.5%, and TurboTrans technology, which lets a single resistor tailor transient response and reduce required output capacitance. Remote sense, output voltage sequencing, and under-voltage lockout support reliable multi-rail systems.
Internally, the PTH04T241W uses a synchronous buck topology with integrated MOSFETs and fixed-frequency PWM control. The TurboTrans control loop optimization allows engineers to meet aggressive load-step requirements typical of modern processors without oversizing capacitors, while the all-ceramic-capacitor optimization lowers ESR-related losses and improves long-term reliability since ceramic capacitors do not wear out like electrolytics.
Typical applications include powering DSPs, FPGAs, ASICs, and microprocessors in networking, telecom, and data-communication equipment, where 3.3V or 5V intermediate buses must be stepped down to low core voltages at ampere-level loads. The compact footprint suits space-constrained line cards and blades.
When designing, size the TurboTrans resistor to the expected load transient, follow datasheet input/output capacitor recommendations, and account for thermal dissipation at high output current using adequate PCB copper area.

Typical Applications
PTH04T241W is suitable for 6 applications: DSP Core Power Supply, FPGA Core and I/O Rails, Telecom and Datacom Line Cards, ASIC and Microprocessor Power, Industrial Point-of-Load Rails, Networking Equipment Processor Rails.
DSP Core Power Supply
The PTH04T241W fits DSP core-rail applications because its 0.69V-3.6V single-resistor adjustable output and ±1.5% total variation meet the tight tolerance windows of modern TI DSP cores, while the 10-A rating covers peak processing loads. In a typical design the module is placed between a 3.3V intermediate bus and the DSP CVDD pin, with remote sense connected at the DSP balls to cancel IR drop across the PCB. TurboTrans resistor selection tunes the control loop to the DSP load-step transient, eliminating oversized bulk capacitance and reducing BOM cost versus a discrete converter solution.
Recommended
FPGA Core and I/O Rails
FPGA VCCINT rails commonly sit between 0.9V and 1.2V at multi-ampere loads; the PTH04T241W delivers up to 10A in this window from a 5V or 3.3V bus at up to 96% efficiency. The all-ceramic capacitor optimization suits FPGA decoupling schemes that already rely on dense ceramic arrays, and TurboTrans lets designers meet nanosecond-class load transients during fabric reconfiguration. Remote sense plus output voltage sequencing support safe multi-rail power-up of core, I/O, and aux rails on the same board without external sequencer ICs.
Recommended
Telecom and Datacom Line Cards
Line cards in telecom and data-communication equipment step a 3.3V or 5V intermediate bus down to processor core voltages in space-constrained footprints. The PTH04T241W's integrated synchronous buck (controller, MOSFETs, inductor, compensation in one module) shortens design cycles versus discrete converters, while its 2nd-generation reduced footprint fits dense blades. Under-voltage lockout and sequencing features improve system reliability, and all-ceramic output design avoids electrolytic capacitor lifetime limits common in always-on telecom equipment operating at elevated ambient temperatures.
Recommended
ASIC and Microprocessor Power
ASIC and microprocessor core supplies demand fast transient response on load steps exceeding 5A per microsecond-class edges. The PTH04T241W addresses this with TurboTrans control-loop optimization, which a single resistor tailors to the specific transient, reducing required output capacitance while keeping the ±1.5% regulation window. Its 2.2V-5.5V input accepts standard intermediate bus voltages, and the remote-sense pin connects at the ASIC power balls to eliminate PCB IR-drop errors that would otherwise erode the tight voltage tolerance budget.
Recommended
Industrial Point-of-Load Rails
Industrial automation boards distribute a 5V rail and derive local low-voltage logic supplies. The PTH04T241W provides a single-package point-of-load solution delivering 10A with up to 96% efficiency, minimizing thermal load inside sealed enclosures. Ceramic-only output capacitance improves vibration reliability versus electrolytic-based designs, and the wide 0.69V-3.6V adjustment range supports legacy 3.3V, 2.5V, and 1.8V rails with one qualified module, reducing BOM variety and requalification effort across product families.
Recommended
Networking Equipment Processor Rails
Routers and switches power network processors and MAC/PHY silicon from a 3.3V distribution bus. The PTH04T241W integrates the entire buck stage in a surface-mount module, cutting layout effort around sensitive high-di/dt loops, an important EMI benefit in dense RF-adjacent networking hardware. Remote sense and output sequencing coordinate with system power managers, and the ±1.5% total variation keeps core rails within specification from cold start through full-traffic thermal soak, supporting long-term uptime requirements of carrier-grade equipment.

Key Differentiators
- All-ceramic output capacitor optimization (vs PTH04T240W)
- TurboTrans transient tuning with one resistor (vs Discrete buck converters)
- Wide 0.69V-3.6V output from one module (vs PTH04T242W)
Design Notes
Place the module with VIN/VOUT pads over solid copper planes and connect remote sense (Sense pin) at the load point, e.g., DSP or FPGA power balls, to cancel PCB IR drop. Keep the TurboTrans resistor trace short and away from switching nodes. Per TI datasheet guidance, follow the recommended land pattern exactly - the integrated inductor means the critical high-di/dt loop is internal, but input ceramic decoupling must sit directly at the VIN pins.
Size the TurboTrans resistor per the datasheet table for the expected load-step amplitude; oversized transients beyond the selected TurboTrans setting will cause excursions outside the ±1.5% window. Ensure the 2.2V-5.5V input bus can source 10A at the output's set voltage including efficiency losses (roughly 10A x VOUT / 0.96 input current at peak).
At 10A with low output voltages such as 1.0V, module dissipation is modest due to synchronous rectification and up-to-96% efficiency, but verify junction temperature using the datasheet thermal derating curves for your airflow condition. Provide adequate PCB copper area under the module; consult the TI datasheet derating graphs rather than assuming full 10A capability in still-air enclosures.
