Step-down power modules

22 March 2017 Power Electronics / Power Management

Texas Instruments introduced a pair of 12 V, 10 A, 4 MHz step-down power modules that require just one external voltage-setting resistor for a complete solution. The easy-to-use SWIFT TPSM84A21 and TPSM84A22 integrate power MOSFETs, shielded inductors, input and output capacitors, and passives into a tiny, low-profile footprint. 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.
