A 1S Direct-Battery-Attach Integrated Buck Voltage Regulator with 5-Stack Thin-Gate 22nm FinFET CMOS Featuring Active Voltage Balancing and Cascaded Self-Turn-ON Drivers
A 1S direct-battery-attach buck converter with a 5-stack, thin-gate-FinFET power train delivers a peak efficiency of 89.2% for a 3.8V in to 1.8V out, with 10x higher power density (~15A/mm2), switching at up to 10x higher frequency (40MHz) using 4x-10x lower inductance (10-100nH) than state of the art. Cascaded self-timed drivers and soft-switching low-side drivers minimize complexity in driving 10 individual power switches safely.
