3 Description
The TPSM82830x is an easy-to-use, synchronous,
step-down, DC/DC module family with integrated
inductor. Based on the DCS-Control topology, the
device provides a fast transient response with small
output capacitance. The internal reference allows to
regulate the output voltage down to 0.5 V with a high
feedback voltage accuracy of 1 over the junction
temperature range of –40°C to 125°C.
The TPSM82830x has a MODE pin to control
the device mode of operation. Power save mode
maintains high efficiency down to very light loads for
extending the system battery run-time. Forced-PWM
mode maintains a continuous conduction mode to
make sure the least ripple in the output voltage and a
quasi-fixed switching frequency. The device features a
Power-Good signal and a well-controlled internal softstart
circuit. The device is able to operate in 100
mode. For fault protection, the device incorporates a
HICCUP short-circuit protection as well as a thermal
shutdown. The family is available in a 3.0 mm× 3.0
mm × 2.0 mm QFN package.
