Texas Instruments TPSM41625 Stackable Power Module

Texas Instruments TPSM41625 Stackable Power Module is an easy-to-use integrated power supply that combines a DC/DC converter with power MOSFETs, a shielded inductor, and passives into a compact QFN package. This TPSM41625 power solution requires few external components while maintaining the ability to adjust key parameters to meet specific design requirements. Applications requiring increased current can benefit from the ability to parallel two TPSM41625 devices.

The TPSM41625 is available in an 11mm × 16mm × 4.2mm, 69-pin QFN package with an optimal layout featuring excellent power dissipation capability, enhancing thermal performance. The package footprint has all signal pins accessible from the perimeter and large thermal pads beneath the device.

The TPSM41625 provides flexibility with many features, including power good signal, clock synchronization, programmable UVLO, soft-start timing selection, pre-bias start-up, and overcurrent/overtemperature protection. These features make the TPSM41625 an ideal product for powering a wide range of devices and systems.
