Product Summary

The LTC3862 is a two phase constant frequency, current mode boost and SEPIC controller that drives N-channel power MOSFETs. Two phase operation reduces system ?ltering capacitance and inductance requirements. The 5V gate drive is optimized for most automotive and industrial grade power MOSFETs.

Adjustable slope compensation gain allows the user to ?ne- tune the current loop gain, improving noise immunity.
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 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
100%new and original,absolutely guarantee!With Entity Authentication and ISCP(In Stock Certified Program).
