LTC3892 Video Product Brief

Sep 18 2017

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 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. For a comparison of the LTC3892 to the LTC3892-1 and LTC3892-2, see Table 1 in the Pin Functions section of the datasheet.
