3 Description
The TPS543B25T is a high-efficiency 18-V, 25-A
synchronous buck converter employing an internally
compensated, fixed-frequency advanced current
mode (ACM) control architecture, which while always
operating under FCCM, generates output voltages
from 0.5 V to 7 V. The device is capable of
providing high efficiency while operating at a switching
frequency up to 2.2 MHz, making the device optimal
for designs requiring a small solution size. The fixed
frequency controller can operate from 500 kHz to
2.2 MHz and can be synchronized to an external
clock using the SYNC pin. Additional features include
a high accuracy voltage reference, two-wire remote
sense, selectable soft-start times, monotonic startup
into prebiased outputs, selectable current limits,
adjustable UVLO through the EN pin, and a full suite
of fault protections.
The TPS543B25T is available in a small 2.5-mm ×
4.5-mm HotRod? WQFN-FCRLF package.
