LM5035B  
PWM Controller with Integrated Half-Bridge and SyncFET  
Drivers  
General Description  
Features  
The LM5035B 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  
Synchronous Rectifiers Turned Off in Shutdown Modes.  
■
■
The LM5035B is a functional variant of the LM5035A half-  
bridge PWM controller. The LM5035B provides higher maxi-  
mum duty cycle and higher start-up regulator output current  
than the LM5035A or LM5035. Also, the Synchronous Recti-  
fier drive outputs of the LM5035B are held low in shutdown  
modes.  
Reduced Deadtime Between High and Low Side Drive for  
Higher Maximum Duty Cycle.  
High Voltage (105V) Start-up Regulator  
■
■
Voltage mode Control with Line Feed-Forward and Volt  
Second Limiting  
Resistor Programmed, 2MHz Capable Oscillator  
■
■
The LM5035, LM5035A, and LM5035B include a floating  
high-side gate driver, which is capable of operating with sup-  
ply voltages up to 105V. Both the high-side and low-side gate  
drivers are capable of 2A peak. An internal high voltage start-  
up regulator is included, along with programmable line un-  
dervoltage lockout (UVLO) and overvoltage protection (OVP).  
The oscillator is programmed with a single resistor to fre-  
quencies up to 2MHz. The oscillator can also be synchronized  
to an external clock. A current sense input and a pro-  
grammable timer provide cycle-by-cycle current limit and ad-  
justable hiccup mode overload protection.  
Programmable Line Under-Voltage Lockout and Over-  
Voltage Protection  
Internal Thermal Shutdown Protection
