3 Description
The TPS562201 and TPS562208 are simple, easy-to-
use, 2-A synchronous step-down converters in SOT-
23 package.
The devices are optimized to operate with minimum
external component counts and also optimized to
achieve low standby current.
These switch mode power supply (SMPS) devices
employ D-CAP2 mode control providing a fast
transient response and supporting both low
equivalent series resistance (ESR) output capacitors
such as specialty polymer and ultra-low ESR ceramic
capacitors with no external compensation
components.
The TPS562201 operates in pulse skip mode, which
maintains high efficiency during light load operation.
The TPS562201 and TPS562208 are available in a 6-
pin 1.6 × 2.9 (mm) SOT (DDC) package and
specified from –40°C to 125°C of junction
temperature.
