LM5035A/LM5035A-1

PWM Controller with Integrated Half-Bridge and SyncFET

Drivers

General Description

Features

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 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. The differences

between LM5035, LM5035A, LM5035B, and LM5035C are

summarized in Table 2.
