FEATURES  
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.
