The is a high-performance step-down Switching Regulator Controller drives an all N-channel synchronous power MOSFET stage. The constant-frequency current-mode architecture allows a phase-lockable frequency of up to 650kHz. The 30µA no-load quiescent current extends operating life in battery powered systems. OPTI-LOOP compensation allows the transient response to be optimized over a wide range of output capacitance and ESR values. The LTC3834-1 features a precision 0.8V reference. The 4 to 36V input supply range encompasses a wide range of battery chemistries. The TRACK/SS pin ramps the output voltage during start-up. Current foldback limits MOSFET heat dissipation during short-circuit conditions.
