4-μA operating quiescent current
1% output voltage accuracy
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.
