The TPSM84A21MOJT is an easy-to-use integrated power solution that combines theTPS54A20, a 10-A, DC/DC, synchronous, step-downconverter with power MOSFETs, shielded inductors, input and output capacitors, and passives into alow profile package. This total power solution requires only one voltage-setting resistor, andeliminates the loop compensation and magnetics part selection from the design process.
The completely integrated power solution allows standard applications to operate with noadditional input or output capacitors and only a single external resistor to set the outputvoltage. High frequency operation, ultra-fast transient response, and accurate voltage regulationallow the TPSM84A21MOJT to meet tight regulation specs.
The 9 × 15 mm PCB footprint is easy to solder onto a printed circuit board and allows acompact, low-profile point-of-load design.
