LM5034 High Voltage Dual Interleaved Current Mode Controller with Active Clamp
LM5034 High Voltage Dual Interleaved Current Mode Controller with Active Clamp
General Description
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.
