3 Description
The TPS56124x is a simple, easy-to-use,
synchronous buck converter with input voltage
ranging from 4.2V to 17V and supports up to 1A
continuous current.
The device is designed to operate with minimum
external component counts and low standby current.
This switch mode power supply (SMPS) device
employs D-CAP3 control mode 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 TPS561243 operates in Eco-mode, which
maintains high efficiency during light load operation.
The TPS561246 operates in FCCM mode, which
keeps the same frequency and lower output ripple
during all load conditions. The TPS56124x integrates
complete protection including OCP, UVLO, OTP, and
UVP with hiccup.
The TPS56224x is available in a 6-pin, 1.6mm
× 1.6mm SOT563 (DRL) package. The junction
temperature is specified from –40°C to 125°C.
