The LTC3828 is a dual high performance step-down switching regulator controller that drives all N-channel synchronous power MOSFET stages. A constant frequency current mode architecture allows for a phase-lockable frequency of up to 550kHz. The TRCKSS pin provides both soft-start and tracking functions. Multiple LTC3828s can be daisy-chained in applications requiring more than two voltages to be tracked.
OPTI-LOOP compensation allows the transient response to be optimized over a wide range of output capacitance and ESR values. The precision 0.8V reference and power good output indicator are compatible with a wide 4.5V to 28V (30V maximum) input supply range, encompassing all battery chemistries.
The RUN pins control their respective channels independently. The FCB/PLLIN pin selects among Burst Mode® operation, skip-cycle mode and continuous current mode. Current foldback limits MOSFET dissipation during short-circuit conditions. Reverse current and current foldback functions are disabled during soft-start.
