TPSM843B22 SWIFT™ Step-Down Power Module

Texas Instruments TPSM843B22 SWIFT™ Step-Down Power Module is a high-efficiency 18V, 20A synchronous buck module employing an internally compensated, fixed-frequency advanced current mode (ACM) control architecture. While the device continuously operates under FCCM, it generates output voltages from 0.5V to 7V. The module can provide high efficiency while operating at a switching frequency of up to 2.2MHz. The Texas Instruments TPSM843B22 is in a 6.5mm x 7.5mm x 4mm over-molded package, which makes it optimal for designs requiring a small solution size. Additional features include a high-accuracy voltage reference, selectable soft-start times, monotonic start-up into pre-biased outputs, selectable current limits, adjustable UVLO through the EN pin, and a full suite of fault protections.
