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.
