LM5035C  
PWM Controller with Integrated Half-Bridge and SyncFET  
Drivers  
General Description  
Features  
The LM5035C 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.  
105V / 2A Half-Bridge Gate Drivers  
■
■
Synchronous Rectifier Control Outputs with  
Programmable Delays  
Reduced Deadtime Between High and Low Side Drive for  
Higher Maximum Duty Cycle.  
■
The LM5035C is a functional variant of the LM5035B half-  
bridge PWM controller. The amplitude of the SR1 and SR2  
waveforms are 5V instead of the Vcc level. Also, the soft-stop  
function is disabled in the LM5035C.  
High Voltage (105V) Start-up Regulator

■
Voltage mode Control with Line Feed-Forward and Volt  
Second Limiting  
The LM5035, LM5035A, LM5035B, and LM5035C include a  
floating high-side gate driver, which 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 pro-  
grammable line undervoltage lockout (UVLO) and overvolt-  
age protection (OVP). 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 and a programmable timer provide cycle-by-cycle cur-  
rent limit and adjustable hiccup mode overload protection.
