LM5035  
PWM Controller with Integrated Half-Bridge and  
SyncFET Drivers  
General Description  
Features  
n 105V / 2A Half-Bridge Gate Drivers  
n Synchronous Rectifier Control Outputs with  
Programmable Delays  
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 volt-  
age feed-forward. The floating high-side gate driver is ca-  
pable 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) and  
overvoltage protection (OVP). The oscillator is programmed  
with a single resistor to frequencies up to 2MHz. The oscil-  
lator 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.  
n High Voltage (105V) Start-up Regulator  
n Voltage mode Control with Line Feed-Forward and Volt  
Second Limiting  
n Resistor Programmed, 2MHz Capable Oscillator  
n Patent Pending Oscillator Synchronization  
n Programmable Line Under-Voltage Lockout  
n Line Over-Voltage Protection  
n Internal Thermal Shutdown Protection  
n Adjustable Soft-Start  
n Versatile Dual Mode Over-Current Protection with  
Hiccup Delay Timer  
n Cycle-by-Cycle Over-Current Protection  
n Direct Opto-coupler Interface  
n 5V Reference Output
