DESCRIPTION  
•
•
Synchronous Rectifiers Turned Off in  
Shutdown Modes.  
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.  
Reduced Deadtime Between High and Low  
Side Drive for Higher Maximum Duty Cycle.  
•
•
High Voltage (105V) Start-up Regulator  
The LM5035B is a functional variant of the LM5035A  
half-bridge PWM controller. The LM5035B provides  
higher maximum duty cycle and higher start-up  
regulator output current than the LM5035A or  
LM5035. Also, the Synchronous Rectifier drive  
outputs of the LM5035B are held low in shutdown  
modes.  
Voltage mode Control with Line Feed-Forward  
and Volt Second Limiting  
•
•
Resistor Programmed, 2MHz Capable  
Oscillator  
Programmable Line Under-Voltage Lockout  
and Over-Voltage Protection  
The LM5035, LM5035A, and LM5035B 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 programmable line undervoltage  
lockout (UVLO) and overvoltage 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 current limit and adjustable hiccup mode  
overload protection.The differences between LM5035,  
LM5035A, LM5035B, and LM5035C are summarized  
in Table 2.
