Texas Instruments TPSM5601R5Hx 1.5A Power Module

Texas Instruments TPSM5601R5Hx 1.5A Power Module is a highly integrated power solution that combines a 60V input, step-down DC/DC converter with power MOSFETs, a shielded inductor, and passives in a thermally-enhanced QFN package. The 5mm × 5.5mm × 4mm, 15-pin QFN package uses Enhanced HotRod QFN technology for enhanced thermal performance, small footprint, and low EMI. The package footprint has all pins accessible from the perimeter and a single large thermal pad for simple layout and easy handling in manufacturing.

The TPSM5601R5Hx is a compact, easy-to-use power module with a wide adjustable output voltage range of 1.0V to 16V. The total solution requires as few as four external components and eliminates the loop compensation and magnetics part selection from the design process. The full feature set includes power good, programmable UVLO, pre-bias start-up, overcurrent, and temperature protections, making the TPSM5601R5Hx an excellent device for powering a wide range of applications. Space-constrained applications benefit from the 5mm × 5.5mm package. Additionally, the Texas Instruments TPSM5601R5HEXT offers an extended low-temperature operation of –55°C, and the TPSM5601R5HS offers frequency spread-spectrum operation.
