3 Description

The TPS543B25E is a high-efficiency, 18V, 25A,

synchronous buck converter. The device employs

an internally compensated, fixed-frequency, ACM

control architecture, which while always operating

under forced continuous conduction mode (FCCM),

generates output voltages from 0.5V to 7V. The

device is capable of providing high efficiency while

operating at a switching frequency up to 2.2MHz,

making the device an excellent choice for designs

requiring a small design size. The fixed frequency

controller can operate from 500kHz to 2.2MHz

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 undervoltage lockout (UVLO) through the

EN pin, and a full suite of fault protections.

The TPS543B25E is available in a small, 2.5mm ×

4.5mm, HotRod™ WQFN-FCRLF package.
