LM5034 High Voltage Dual Interleaved Current Mode Controller

LM5034 High Voltage Dual Interleaved Current Mode Controller

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 in.

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 inclu.
