.. LM5032 High Voltage Dual Interleaved Current Mode Controller March 2005 LM5032 High Voltage Dual Interleaved Current Mode Controller General 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 prised 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 pound (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 switches. Additional Features include programmable line under-voltage lockout, cycle-by-cycle current limit, hiccup mode fault operation with adjustable response time, PWM slope pensation, soft-start, and a 2 MHz capable oscillator with synchronization capability.
