TPSM8282x Step-Down Converter Power Modules Texas Instruments TPSM8282x Step-Down Converter Power Modules are 1A and 2A step-down converters in a MicroSiP™ power module optimised for small solution size and high efficiency. The TI power modules integrate a synchronous step-down converter and an inductor to simplify design, reduce external components, and save the PCB area. The low-profile and compact solution are suitable for automated assembly by standard surface-mount equipment. To maximise efficiency, the converter operates in PWM mode with a nominal switching frequency of 4MHz and automatically enters Power-Save Mode operation at light load currents.
