The TLVM13630 power module is a highly integrated 3-A power solution that combines a 36-V input, step-down DC/DC converter with integrated power MOSFETs, a shielded inductor, and passives in a thermally enhanced QFN package. The 30-pin QFN package has enhanced thermal performance, a small footprint, and low EMI. The package footprint has all signal and power pins accessible from the perimeter and four larger thermal pads beneath the device for simple layout and easy handling in manufacturing.

The TLVM13630 is a compact, easy-to-use power module with a wide output voltage range that can be adjusted from 1 V to 6 V. The module is designed to quickly and easily implement a power design in a small PCB footprint. The total solution requires as few as four external components and eliminates the loop compensation and magnetics part selection from the design process.

Although designed for small size and simplicity, the TLVM13630 offers many features including precision enable with hysteresis that allows external adjustable UVLO and a power-good indicator that allows sequencing and output voltage monitoring. The small package size is a good fit for space-constrained applications.
