  • Product Description:

    The CD5034 dual current mode PWMcontroller contains all the features needed tocontrol either two independent forward activeclamp DC/DC converters or a single highcurrent converter comprised of two interleavedpower stages. The two controller channelsoperate 180°out of phase thereby reducinginput ripple current.The CD5034 includes a startup regulator thatoperates over a wide input range up to100Vand compound (bipolar + CMOS) gate driversthat provide a robust 2.5A peak sink current.The adjustable dead-time of the active clampgate drivers and adjustable maximum PWMduty cycle reduce stress on the primary sideMOSFET switches. Additional features includeprogrammable line under-voltage lockout,cycle-by-cycle current limit, hiccup mode faultoperation with adjustable restart delay, PWMslope compensation, soft-start and oscillatorsynchronization capability.
