- Current-mode PWM control with optional PFM for high efficiency across load ranges from milliamps to full load
- Compact 8-pin VSON (R-PDSO-F8) package enabling high-power-density point-of-load regulators on tight PCB layouts
Applications
The TPS563300DRLR is used in industrial 24 V rail point-of-load regulators, automotive body electronics, and IoT gateway power supplies requiring a wide input range down to 3.8 V. Its PFM mode sustains high efficiency at light loads, making it well suited for battery-assisted designs that sleep most of the time. Telecom and networking equipment powered from a 12 V or 24 V bus also benefit from its current-mode control for fast transient response.

Frequently Asked Questions
What input voltage range does TPS563300DRLR support, and which industrial bus voltages does it cover?
The TPS563300DRLR accepts input voltages from 3.8 V to 28 V, with a nominal 24 V operating point. This range covers 5 V USB, 12 V ATX, and 24 V industrial control bus voltages in a single design, eliminating the need for input pre-regulators in mixed-voltage panel boards.
How does PFM mode in TPS563300DRLR improve system efficiency compared to fixed-frequency PWM for a battery-backed IoT node?
In PFM (pulse-frequency modulation) mode, TPS563300DRLR reduces switching frequency at light loads below roughly 10% of full load, cutting switching losses and achieving efficiencies above 85% at 1 mA to 10 mA. For an IoT node drawing 5 mA in sleep mode from a 12 V rail, this can extend battery life by 2x compared to a fixed 600 kHz PWM regulator.
What is the control architecture of TPS563300DRLR, and why does current-mode control benefit designs with fast load transients?
TPS563300DRLR uses current-mode PWM control, which adds an inner current-feedback loop that responds to load transients within a single switching cycle. This results in output voltage deviation of typically less than 50 mV for a 500 mA load step, making it suitable for FPGA core rail supplies that switch between 50 mA idle and 300 mA active currents in under 1 µs.
For an automotive 24 V body-electronics board, how does TPS563300DRLR handle load-dump transients near its 28 V maximum input?
The 28 V absolute maximum input rating is close to the 26 V ISO 7637 load-dump level after a transient clamp. Designers should add a TVS diode rated at 26 V before the input pin to suppress spikes exceeding 28 V, keeping the regulator within its safe operating area. A 10 µF ceramic bypass cap at the input also reduces peak stress during fast transients under 1 µs.
What package does TPS563300DRLR use, and what thermal management approach is recommended at full load?
TPS563300DRLR is housed in an 8-pin VSON (R-PDSO-F8) package with an exposed thermal pad, measuring approximately 3 mm x 3 mm. For continuous operation near the maximum output current of 3 A, connecting the exposed pad to a 2 cm² copper pour on the PCB top layer reduces junction temperature by roughly 15°C compared to no thermal relief, keeping Tj below 125°C at 25°C ambient.
