3 Description
The TPS562200 and TPS563200 are simple, easy-to-
use, 2 A and 3 A synchronous step-down (buck)
converters in 6 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.
TPS562200 and TPS563200 operate in Advanced
Eco-mode, which maintains high efficiency during
light load operation. The devices are available in a 6-
pin 1.6mm x 2.9mm SOT (DDC) package, and
specified from –40°C to 85°C of ambient temperature.
