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.
