LM5035A-1 - PWM Controller

Download the LM5035A-1 datasheet PDF. This datasheet also covers the LM5035A variant, as both devices belong to the same pwm controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The LM5035A Half-Bridge Controller/Gate Driver contains all of the

Key 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:.
