3 Description
The TPS562210 and TPS563210 are simple, easy-to-
use, 2 A, 3 A synchronous step-down converters in 8
pin 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 devices operate in Advanced Eco-mode™, which
maintains high efficiency during light load operation.
The TPS562210 and TPS563210 are available in a 8-
pin 1.6 × 2.9 (mm) SOT (DDF) package, and
specified from –40°C to 85°C of ambient temperature.
