3 Description

The TPS6208xx device family is a high-frequency

synchronous step-down converters optimized for

small solution size and high efficiency. With an

input voltage range of 2.4 V to 5.5 V, common

battery technologies are supported. At medium

to heavy loads, the converter operates in PWM

mode and automatically enters power save mode

operation at light load to maintain high efficiency

over the entire load current range. The forced PWM

version of the device maintains a CCM operation

across any load. The 4-MHz switching frequency

allows the device to use small external components.

Together with its DCS-control architecture, excellent

load transient performance, and output voltage

regulation accuracy are achieved. Other features like

overcurrent protection, thermal shutdown protection,

active output discharge, and power good are built in.

The device is available in a 6-pin WCSP package.
