Product Overview

The LT3692AEFE#PBF is a dual current mode PWM step-down DC/DC Converter with two internal 3.8A switches. Independent input voltage, shutdown, feedback, soft-start, UVLO current limit and comparator pins for each channel simplify complex power supply tracking and sequencing requirements. To optimize efficiency and component size, both converters have a programmable maximum current limit and are synchronized to either a common external clock input or a resistor settable fixed 250kHz to 2MHz internal oscillator. A frequency divider is provided for channel 1 to further optimize component size. At all frequencies, a 180° phase relationship between channels is maintained, reducing voltage ripple and component size. A clock output is available for synchronizing multiple regulators. Minimum input to output voltage ratios are improved by allowing the switch to stay on through multiple clock cycles only switching off when the boost capacitor needs recharging.
  • Die temperature monitor
  • Independent synchronized switching frequencies optimize component size
  • Antiphase switching
  • Outputs can be paralleled
  • Flexible output voltage tracking
  • 95% Maximum duty cycle low dropout
