3 Description

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.
