What are the key features of XTPS56637RPAT?
- 4.5 V to 28 V wide input range and 6 A continuous output current in a compact 10-pin VSON package for multi-rail power designs
- ULQ-mode ultra-light-load operation extending efficiency at sub-100 mA loads in always-on IoT and industrial systems
- Adjustable output voltage from 0.6 V to 16 V via external resistor divider covering processor core, I/O, and memory rails
- PWM control with integrated high-side and low-side MOSFETs delivering high conversion efficiency at up to 2.2 MHz switching frequency
What is XTPS56637RPAT used for?
The XTPS56637RPAT is well suited for 12 V and 24 V rail step-down regulators supplying FPGA core voltages, microprocessor I/O rails, and industrial sensor power in space-constrained PCB designs. Its 4.5 V to 28 V input tolerance makes it directly compatible with 24 V industrial bus supplies, telecom intermediate bus architectures, and automotive 12 V systems. The ULQ-mode light-load efficiency is particularly valuable for always-on subsystems in industrial gateways, smart meters, and battery-backed control units.

Frequently Asked Questions
What input voltage range does XTPS56637RPAT support and which supply rails is it compatible with?
The XTPS56637RPAT accepts an input voltage from 4.5 V to 28 V, making it compatible with 5 V USB power, 12 V ATX rails, and 24 V industrial bus supplies. With a 6 A output current capability and adjustable output down to 0.6 V, it can serve as a point-of-load regulator for FPGAs and processors drawing significant current from high-voltage rails.
How does ULQ-mode in XTPS56637RPAT improve system-level efficiency in always-on industrial equipment?
ULQ-mode (ultra-light-load quiescent mode) reduces the switching frequency and quiescent current at loads below approximately 100 mA, maintaining converter efficiency above 80% even at standby currents of a few milliamperes. In always-on industrial gateways or smart meters drawing 50 mA at idle from a 12 V rail, this mode can cut standby power loss by more than 50% compared to fixed-frequency operation.
What output voltage range can be configured on XTPS56637RPAT and how is it set?
The XTPS56637RPAT output voltage is adjustable from 0.6 V to 16 V using an external resistor divider connected to the feedback pin. This covers common logic rails including 0.75 V, 1.0 V, 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5 V, as well as intermediate bus voltages up to 16 V, without changing the switching topology or requiring different hardware.
How does XTPS56637RPAT compare in output current and package size to TPS56339 for a 12 V to 3.3 V conversion?
The XTPS56637RPAT delivers 6 A continuous output versus the 3 A rating of TPS56339, making it more suitable for loads above 3 A such as FPGA I/O banks or multi-channel analog front-ends. Both parts use similar VSON packages, but the XTPS56637RPAT's 10-pin VSON provides a slightly larger thermal pad area to manage the higher 6 A dissipation from a 12 V input rail.
