The SWIFT TPSM84A21 and TPSM84A22 dc/dc modules integrate power
MOSFETs, shielded inductors, input and output capacitors, and passives into a 2.3-mm high package. The solution is offered in a 9 x 15-mm module with
a single external voltage-setting resistor that makes up a complete solution
footprint of 11 x 15 mm. In addition, it provides 1% overshoot in transient conditions
without special magnetics or additional capacitors.

By using the step-down power module together with TI’s WEBENCH
Power Designer, engineers can get their space-constrained point-of-load (POL)
telecom, networking, and test and measurement power-supply designs to market
faster. TI will demonstrate the TPSM84A22 module in its booth (No. 701) at the
Applied Power Electronics Conference (APEC), March 27-29 in Tampa, Florida.

 

Unlike other 10-A step-down modules available today, the highly
integrated TPSM84A21
and TPSM84A22
require just one external voltage-setting resistor for a complete 12-V
step-down power solution. For an application such as powering tightly regulated
field-programmable gate array (FPGA) rails, a typical 10-A module would require
up to 16 external capacitors. In comparison, the TPSM84A21 provides low output
ripple due to the 4-MHz switching frequency and integrated 185 μF of output
capacitance, which maintains regulation accuracy without any external capacitors.
The
TPSM84A21 with a voltage output of 0.55 to 1.35 V and the TPSM84A22 with a
voltage output of 1.2 to 2.0 V are available in volume now.
