Texas Instruments LM5034MTC/NOPB

The LM5034 dual current mode PWM controller contains all the features needed to control either two independent forward/active clamp dc/dc converters or a single high current converter comprised of two interleaved power stages. The two controller channels operate 180° out of phase thereby reducing input ripple current. The LM5034 includes a startup regulator that operates over a wide input range up to 100V and compound (bipolar + CMOS) gate drivers that provide a robust 2.5A peak sink current. The adjustable dead-time of the active clamp gate drivers and adjustable maximum PWM duty cycle reduce stress on the primary side MOSFET switches. Additional features include programmable line under-voltage lockout, cycle-by-cycle current limit, hiccup mode fault operation with adjustable restart delay, PWM slope compensation, soft-start, and a 2 MHz capable oscillator with synchronization capability.
