The integrated 36V, 4A DC/DC solution combines power MosFETs, shielded inductors, and passivity

The Texas Instruments TPSM63604 Synchronous Stepdown Power Module is a highly integrated 36V, 4A DC/DC solution that combines power MosFEts, shielded inductors and passives in the enhanced HotRod QFN package. The module has V(IN) and V(OUT) pins located at the corners of the package to optimize input and output capacitance placement. Four larger heat pads below the module make the layout simple and easy to operate in manufacturing.

With output voltages ranging from 1V to 16V, TI TPSM63604 enables fast and easy low EMI designs in small PCB footprint. The overall solution requires only four external components and eliminates the choice of magnetic and compensating parts in the design process.

The TPSM63604 module, while designed for small size and simplicity in space-constrained applications, offers many robust performance features: precision support for adjustable input voltage UVLO lag, resistance programmable switching node turn rate, improved EMI, integrated V(CC), power-up, and input capacitance, improved reliability and higher density, Constant switching frequency over full load current range, negative output voltage capability, and a PGOOD indicator for sequencing, fail-safe, and output voltage monitoring
