Texas Instruments introduced a pair of 12 V, 10 A, 4 MHz step-down power modules that provide a power management solution that it claimed at the time was 20% smaller than any similar solution available. By using them 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.
The easy-to-use SWIFT TPSM84A21 and TPSM84A22 DC-DC modules integrate power MOSFETs, shielded inductors, input and output capacitors, and passives into a tiny, low-profile footprint. In addition, it provides as little as 1% overshoot in transient conditions without special magnetics or additional capacitors.
Unlike other 10 A, 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 ultra-low output ripple due to the very high 4 MHz switching frequency and integrated 185 μF of output capacitance, which maintains regulation accuracy without any external capacitors.
