The TPS564201 is a simple, easy-to-use, 4-A synchronous step-down converter in SOT-23package.

The device is optimized to operate with minimum external component count and alsooptimized to achieve low standby current.

These switch mode power supply (SMPS) devices employ D-CAP2 mode control providing a fasttransient response and supporting both low-equivalent series resistance (ESR) output capacitorssuch as specialty polymer and ultra-low ESR ceramic capacitors with no external compensationcomponents.

The TPS564201 operates in pulse skip mode, maintaining highefficiency during light load operation. The TPS564201 is available in a 6-pin 1.6-mm × 2.9-mm SOT (DDC) package, and specifiedfrom a –40°C to 125°C junction temperature.
