LM5032 - High Voltage Dual Interleaved Current Mode Controller
National Semiconductor (Texas Instruments)
Description
The LM5032 dual current mode PWM controller contains all the
Features
needed to control either two independent forward 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 LM5032 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 maximum PWM duty cycle reduce stress on the primary side MOSFET switch.
