3 Description

The TPS6208xx device family is a high-frequency,

synchronous step-down converter designed for small

design size and high efficiency. With an input

voltage range of 2.4V to 5.5V, 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 4MHz switching frequency allows

the device to use small external components.

Together with 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.
