The 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.
