LTC3892EFE-1#TRPBF

The LTC�3892/LTC3892-1 is a high performance dual step-down DC/DC switching regulator controller that drives all N-channel synchronous power MOSFET stages. Power loss and noise are minimized by operating the two controller output stages out-of-phase. The gate drive voltage can be programmed from 5V to 10V to allow the use of logic or standard-level FETs and to maximize efficiency. Internal switches in the top gate drivers eliminate the need for external bootstrap diodes. A wide 4.5V to 60V input supply range encompasses a wide range of intermediate bus voltages and battery chemistries. Output voltages up to 99% of VIN can be regulated. OPTILOOP � compensation allows the transient response and loop stability to be optimized over a wide range of output capacitance and ESR values. The 29μA no-load quiescent current extends operating run time in battery powered systems.
