Key Features
- 15 A continuous output current with integrated MOSFETs in a 24-pin QFN (4 mm × 5 mm) package for high-density power designs
- Wide 2.7 V to 16 V input voltage range supporting 3.3 V, 5 V, and 12 V bus architectures with voltage-mode PWM control
- Programmable soft-start, overcurrent protection, and power-good output simplifying system-level power sequencing
Applications
TPS548A28RWWR is designed for point-of-load power conversion in cloud servers, network switches, and SSD storage arrays where a 12 V bus must be stepped down to 1 V to 3.3 V at up to 15 A with minimal board area. Its high switching frequency capability reduces output inductor and capacitor size, making it ideal for dense PCB layouts in FPGAs and DSP core supply rails. It is also used in test-and-measurement instruments and industrial computing modules requiring precise output voltage regulation under dynamic load transients.

Frequently Asked Questions
What is the maximum continuous output current and input voltage range for TPS548A28RWWR?
TPS548A28RWWR delivers up to 15 A continuous output current from a 2.7 V to 16 V input, covering standard 5 V and 12 V bus rails in server, networking, and industrial applications with fully integrated high-side and low-side switch MOSFETs.
Which control architecture does TPS548A28RWWR use, and how does this affect loop compensation?
TPS548A28RWWR uses voltage-mode PWM control, which provides excellent noise immunity and deterministic switching frequency; designers set the compensation network externally using resistor-capacitor networks on the COMP pin to optimize transient response for output capacitances ranging from 100 µF to over 1000 µF.
How compact is the TPS548A28RWWR package, and what thermal performance does it offer at 15 A?
The device is housed in a 24-pin QFN package measuring approximately 4 mm × 5 mm, and its exposed thermal pad enables junction-to-board thermal resistance below 5 °C/W on a 4-layer PCB, supporting up to 15 A output at ambient temperatures up to 85 °C with adequate airflow.
For a 12 V to 1.0 V conversion at 15 A, what efficiency advantage does TPS548A28RWWR offer over a discrete FET solution?
TPS548A28RWWR integrates optimized low-RDS(on) MOSFETs (typically under 5 mΩ for the low-side switch), achieving peak efficiencies above 90% at 12 V input, 1.0 V output, 15 A — eliminating the gate-drive losses and layout parasitics that commonly reduce efficiency by 2 % to 4 % in discrete-FET designs.
