The TPSM84A21 is an easy-to-use integrated power solution that combines the TPS54A20, a 10-A, DC/DC, synchronous, step-down converter with power MOSFETs, shielded inductors, input and output capacitors, and passives into a low profile package. This total power solution requires only one voltage-setting resistor, and eliminates the loop compensation and magnetics part selection from the design process.

The completely integrated power solution allows standard applications to operate with no additional input or output capacitors and only a single external resistor to set the output voltage. High frequency operation, ultra-fast transient response, and accurate voltage regulation allow the TPSM84A21 to meet tight regulation specs.

The 9 × 15 mm PCB footprint is easy to solder onto a printed circuit board and allows a compact, low-profile point-of-load design.
