4-V to 18-V input, 12-A synchronous SWIFT™ step-down power module with extended temperature

The TPSM843A22E is a

high-efficiency 18-V, 12-A synchronous buck module 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 module is capable of providing high efficiency while

operating at a switching frequency up to 2.2 MHz. The module is in a 6.5-mm x 7.5-mm

x 4-mm 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 prebiased outputs, selectable

current limits, adjustable UVLO through the EN pin, and a full suite of fault

protections.
