Product Overview

The LTC3814EFE-5#PBF is a synchronous step-up Switching Regulator Controller can generate output voltages up to 60V. The LTC3814-5 uses constant off-time peak current control architecture to deliver very high 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 LTC3814-5 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 LTC3814-5 to be turned off reducing the supply current to <230µA.
  • Large 1R Gate drivers
  • No current sense resistor required
  • Dual N-channel MOSFET synchronous drive
  • ±0.5% 0.8V Voltage reference
  • Fast transient response
  • Programmable soft-start
  • Generates 5.5V Driver supply
  • Power good output voltage monitor
  • Adjustable cycle-by-cycle current limit
  • Undervoltage lockout on driver supply
  • Output overvoltage protection
