High Voltage Dual Interleaved Current Mode Controller With Active Clamp

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.
