TPSM843320 is a highly efficient, small, and flexible synchronous step-down DC-DC converter in a MicroSiP power module package that is easy to use. The module operates up to 18-V input with fixed-frequencies that are resistor adjustable by system designer. The embedded IC is internally compensated which reduces external components and design size. The integrated high-frequency capacitor reduces the transient peak at switching node.

The TPSM843320 module employs an internally compensated, fixed-frequency advanced current mode control. The device is capable of providing high efficiency while running at a switching frequency up to 2.2 MHz. 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, 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.
