Description

The TPSM86838 is a high efficiency, high-voltage input, easy-to-use synchronous buck power module. The device integrates power MOSFETs, a shielded inductor and basic passives, minimizing the solution-size. With the wide operating input voltage range of 4.5 V to 28 V, the TPSM86838 is designed for systems powered from 12-V, 19-V, 24-V power-bus rails. The device supports up to 8-A continuous output current. The output voltage range is from 0.6 V to 5.5 V. The TPSM86838 device provides 800-kHz and 1.2-MHz switching frequencies for selection. D-CAP3™ control mode provides an easy-to-design, stable regulation with very little external components, and supports cost-effective ceramic capacitors.
