Description

General part information

LTC3862-1 Series

The LTC3862-1 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. 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 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 NumberVINRangeINTVCCUV+UV–LTC38624V to 36V5V3.3V2.9VLTC3862-18.5V to 36V10V7.5V7.0VLTC3862-25.5V to 36V10V4.4V3.9VApplicationsAutomotive, Telecom and Industrial Power Supplies
