Product Overview

The LTC3892HUH#PBF is a high-performance dual step-down DC/DC Switching Regulator Controller 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 5 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 4.5 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.
  • No external bootstrap diodes required
  • Selectable gate drive UVLO thresholds
  • Out-of-phase operation reduces required input capacitance and power supply induced noise
  • Selectable continuous, pulse skipping or low ripple burst mode operation at light loads
  • 3.6µA Low shutdown IQ
