The LTC3734 is a single-phase synchronous step-down switching regulator controller that drives all N-channel power MOSFETs in a constant frequency architecture. The output voltage is programmable by six VID bits during normal operation and by external resistors during initial boot-up and deeper sleep state. The LTC3734 drives its output stage at frequencies up to 550kHz. Powerful onchip gate drivers eliminate the need for external gate driver ICs, thus simplifying the design.
An Intel compatible PSIB input is provided to select between two modes of operation. Fully enhanced synchronous mode achieves a very small output ripple and very fast transient response while power saving mode realizes very high efficiency. OPTI-LOOP® compensation allows the transient response to be optimized for a wide range of output capacitance and ESR values.
The LTC3734 is available in a small 5mm × 5mm QFN package. For 2-phase applications refer to the LTC3735.
