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 the company claimed at the time was four times higher than any other 12 V power management component or solution available.
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.
The device features a unique two-phase, series-capacitor buck topology that merges a switched-capacitor circuit with a multiphase buck converter. This capacitive conversion technology enables efficient, high-frequency operation and measures as much as seven times smaller than conventional converters.
Small HotRod quad flat no-lead (QFN) packaging and inexpensive, tiny 2 to 5 MHz inductors enable a 131 mm² solution size, while the TPS54A20’s 2 mm profile allows
placement of tiny 10 A voltage regulators on the back side of a printed circuit board.
A 14 ns minimum on-time allows for 4 MHz, 7 MHz or 10 MHz operation without compromising efficiency or electromagnetic interference (EMI) performance.
