LTC3892 Datasheet 2-phase Synchronous Step-down DC/dc Controller

Manufacturer: Linear Technology (now Analog Devices)

General Description

The LTC®3892/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.

Key Features

  • nn Wide VIN Range: 4.5V to 60V (65V Abs Max) nn Wide Output Voltage Range: 0.8V ≤ VOUT ≤ 99%.
  • VIN nn Adjustable Gate Drive Level 5V to 10V (OPTI-DRIVE) nn No External Bootstrap Diodes Required nn Low Operating IQ: 29μA (One Channel On) nn Selectable Gate Drive UVLO Thresholds nn Out-of-Phase Operation Reduces Required Input Capacitance and Power Supply Induced Noise nn Phase-Lockable Frequency: 75kHz to 850kHz nn Selectable Continuous, Pulse Skipping or Low Ripple Burst Mode® Operation.
