DESCRIPTION

The LM5039 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 feed-forward. The

LM5039 is a functional variant of the LM5035B half-

bridge PWM controller, featuring average current limit

during an overload event to balance the center-point

of the half-bridge capacitor divider. The floating high-

side gate driver is capable of operating with supply

voltages up to 105V. Both the high-side and low-side

gate drivers are capable of 2A peak. An internal high

voltage startup regulator is included, along with

programmable line undervoltage lockout (UVLO). The

oscillator is programmed with a single resistor to

frequencies up to 2MHz. The oscillator can also be

synchronized to an external clock. A current sense

input provides peak cycle-by-cycle and average

current limit. Other features include adjustable hiccup

mode overload protection, soft-start, revision

reference, and thermal shutdown.
