Description

General part information

LTC3862-2 Series

The LTC3862-2 is a two-phase constant frequency, current mode boost and SEPIC 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 75kHz to 500kHz range and can be synchronized to an external clock using the internal PLL. Multiphase 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 10V 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.Part NumberVin RangeINTVccUV+UV-LTC38624V to 36V5V3.3V2.9VLTC3862-18.5V to 36V10V7.5V7.0VLTC3862-25.5V to 36V10V4.4V3.9VApplicationsAutomotive, Telecom and Industrial Power Supplies
