3 Description
The TPS565201 is a simple, easy-to-use, 5-A
synchronous step-down converter.
The device is optimized to operate with minimum
external component counts and also optimized to
achieve low standby current.
This switch mode power supply (SMPS) device
employs D-CAP2™ control, which provides fast
transient response and requires no external
compensation components. D-CAP2 also allows the
use of low-equivalent series resistance (ESR)
specialty polymer capacitors and ceramic output
capacitors.
The TPS565201 operates in pulse skip mode,
maintaining high efficiency during light load operation.
The TPS565201 device is available in a 6-pin 1.6-mm
× 2.9-mm SOT (DDC) package, and operates over a
–40°C to 125°C junction temperature range.
