Product Overview

The LTC3812EFE-5#PBF is a synchronous step-down Switching Regulator Controller can directly step down voltages from up to 60V input, making it ideal. The LTC3812-5 uses constant on-time valley current control architecture to deliver very low duty cycles with accurate cycle-by-cycle current limit without requiring a sense resistor. A precise internal reference provides 0.5% DC accuracy. A high bandwidth (25MHz) error amplifier provides very fast line and load transient response. Large 1R gate drivers allow the LTC3812-5 to drive large power MOSFETs for higher current applications. The operating frequency is selected by an external resistor and is compensated for variations in VIN. A shutdown pin allows the controller to be turned off reducing the supply current to <230µA. Integrated bias control generates gate drive power from the input supply during start-up and when an output short-circuit occurs. When in regulation, power is derived from the output for higher efficiency.
  • Large 1R Gate drivers
  • No current sense resistor required
  • Dual N-channel MOSFET synchronous drive
  • Extremely fast transient response
  • Programmable soft-start
  • Selectable pulse-skipping mode operation
  • Power good output voltage monitor
  • Adjustable cycle-by-cycle current limit
  • Undervoltage lockout on driver supply
  • Output overvoltage protection
