The LTC3736 is a 2-phase dual synchronous step-down switching regulator controller with tracking that drives external complementary power MOSFETs using few external components. The constant frequency current mode architecture with MOSFET VDS sensing eliminates the need for sense resistors and improves efficiency. Power loss and noise due to the ESR of the input capacitance are minimized by operating the two controllers out of phase.
Burst Mode operation provides high efficiency at light loads. 100% duty cycle capability provides low dropout operation, extending operating time in battery-powered systems.
The switching frequency can be programmed up to 750kHz, allowing the use of small surface mount inductors and capacitors. For noise sensitive applications, the LTC3736 switching frequency can be externally synchronized from 250kHz to 850kHz. Burst Mode operation is inhibited during synchronization or when the SYNC/FCB pin is pulled low in order to reduce noise and RF interference. Automatic softstart is internally controlled.
The LTC3736 is available in the tiny thermally enhanced (4mm × 4mm) QFN package or 24-lead SSOP narrow package.
