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.
