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
switches. Additional features include programmable line
under-voltage lockout, cycle-by-cycle current limit, hiccup
mode fault operation with adjustable response time, PWM
slope compensation, soft-start, and a 2 MHz capable oscillator
with synchronization capability.
