SNVS428H – JANUARY 2006 – REVISED OCTOBER 2015 LM5035 PWM Controller With Integrated Half-Bridge and SyncFET Drivers
1 Features 3 Description The LM5035 half-bridge controller-gate driver
contains all of the features necessary to implement
half-bridge topology power converters using voltage
mode control with line voltage feedforward. The
floating high-side gate driver is capable of operating
with supply voltages up to 105 V. Both the high-side
and low-side gate drivers are capable of 2-A peak. An
internal high voltage start-up regulator is included,
along with programmable line undervoltage lockout
(UVLO) and overvoltage protection (OVP). The
oscillator is programmed with a single resistor to
frequencies up to 2 MHz. The oscillator can also be
synchronized to an external clock. A current sense
input and a programmable timer provide cycle-bycycle current limit and adjustable hiccup mode
overload protection. 1 105-V, 2-A Half-Bridge Gate Drivers
