The TPSM8282x device family consists of a 1-A, 2-
A, and 3-A step-down converter MicroSiP™ power
modules optimized for small solution size and high
efficiency.
The power modules integrate a synchronous step-
down converter and an inductor to simplify design,
reduce external components and save PCB area.
The TPSM8282x is available in two flavors. The
first includes an automatically entered power save
mode to maintain high efficiency down to very light
loads for extending the system battery run-time. The
second version, the TPSM8282xA, runs in forced-
PWM maintaining a continuous conduction mode at
all currents to minimize the output ripple. In PWM
mode the converter operates with a nominal switching
frequency of 4MHz.

In power save mode, the device operates with
typically 4-µA quiescent current. Using the DCS-
Control topology, the device achieves excellent
load transient performance and accurate output
voltage regulation. The EN and PG pins, which
support sequencing configurations, bring a flexible
system design. An integrated soft start-up reduces
the inrush current required from the input supply.
Overtemperature protection and hiccup short circuit
protection deliver a robust and reliable solution.
