Product Overview

The LTC3862HGN#PBF is a 2-phase current-mode step-up DC/DC Controller that drives N-channel power MOSFETs. Two phase operation reduces system filtering capacitance and inductance requirements. The operating frequency can be set with an external resistor over a 75 to 500kHz range and can be synchronized to an external clock using the internal PLL. Multi-phase operation is possible using the SYNC input, the CLKOUT output and the PHASEMODE control pin allowing 2-, 3-, 4-, 6- or 12-phase operation. Other features include an internal 5V LDO with undervoltage lockout protection for the gate drivers, a precision RUN pin threshold with programmable hysteresis, soft-start and programmable leading edge blanking and maximum duty cycle.
  • 2-phase Operation reduces input and output Capacitance
  • Fixed frequency, peak current mode control
  • 5V Gate drive for logic-level MOSFETs
  • Adjustable slope compensation gain
  • Up to 96% adjustable maximum duty cycle
  • Adjustable leading edge blanking
  • ±1% Internal voltage reference
  • Internal 5V LDO regulator
