Design LM5032
SNVS344B – MARCH 2005 – REVISED DECEMBER 2014 LM5032 High-Voltage Dual Interleaved Current Mode Controller
1 Features 3 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 180В° out
of phase thereby reducing input ripple current. The
LM5032 includes a startup regulator that operates
over a wide input range up to 100 V and compound
(bipolar + CMOS) gate drivers that provide a robust
2.5-A peak sink current. The adjustable maximum
PWM duty cycle reduce stress on the primary side
MOSFET switches. Additional features include
programmable line undervoltage lockout, cycle-bycycle current limit, hiccup mode fault operation with
adjustable response time, PWM slope compensation,
soft-start, and a 2-MHz capable oscillator with …
