Description
General part information
LTC3892 Series
The LTC3892/LTC3892-1/LTC3892-2 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 VINcan be regulated. OPTI-LOOP®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.ApplicationsAutomotive and Industrial Power SystemsDistributed DC Power SystemsHigh Voltage Battery Operated Systems
