FEATURES  
DESCRIPTION  
The LM5035A 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  
LM5035A is a functional variant of the LM5035 half-  
bridge PWM controller. The VCC current limit  
threshold has been increased to 35 mA. The soft start  
and soft start currents have been increased from 50  
µA to 100 µA. The BST UV threshold has been  
lowered to less than the VCC UV threshold. The ratio  
of the T1 and T2 delays on the SR1 and SR2 outputs  
has been increased from 2:1 to 3:1. 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) 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.
