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-by-cycle current limit and adjustable hiccup
mode overload protection.
