The TPSM63603 power module is a highly integrated 3-A power solution that combines a 36-V input, step-down DC/DC converter with power MOSFETs, a shielded inductor, and passives in a thermally enhanced QFN package. The 30-pin QFN package has enhanced thermal performance, small footprint, and low EMI. The package footprint has all signal and power pins accessible from the perimeter as well as four larger thermal pads beneath the device for simple layout and easy handling in manufacturing.
The TPSM63603 is a compact, easy-to-use power module with a wide output voltage range of 1.0 V to 16 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 TPSM63603 offers many features: precision enable with hysteresis allows external adjustable UVLO, adjustable SW node slew rate for improving EMI, and a power-good indicator allows sequencing and output voltage monitoring. The small package size is a good fit for space-constrained applications.
