This capacitive conversion technology enables efficient, high-frequency operation and measures as much as seven times smaller than conventional converters. The TPS54A20 features a unique two-phase, series-capacitor DC/DC buck topology that merges a switched-capacitor circuit with a multiphase buck converter. By using the step-down converter together with TI’s WEBENCH Power Design tool, engineers can get their space- and height-constrained point-of-load (POL) telecom and networking power-supply designs to market faster. ![]() ![]() The unique topology of the TPS54A20 SWIFT synchronous DC/DC converter enables high-frequency operation at up to 5 MHz per phase without special magnetics or compound semiconductors, which designers can use for 8-V to 14-V input and 10-A output applications. Texas Instruments introduced the industry’s first 12-V, 10-A, 10-MHz series-capacitor buck converter that achieves more than 50 A/cm3 in current density, which is four times higher than any other 12 V power management component or solution available today.
