Overview

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. The LM5035B is a functional variant of the LM5035A halfbridge PWM controller.

  • 105V / 2A Half-Bridge Gate Drivers
  • Synchronous Rectifier Control Outputs with Programmable Delays
  • Synchronous Rectifiers Turned Off 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
  • Programmable Line Under-Voltage Lockout and OverVoltage Protection
  • Internal Thermal Shutdown Protection
  • Adjustable Soft-Start
