TPSM843820 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 18V 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 TPSM843820 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 2.2MHz. 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, 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.
