LM5036 (ACTIVE)

Half-Bridge PWM Controller With Integrated Auxiliary Bias Supply

 

Description

The LM5036 device is a highly integrated PWM controller with integrated auxiliary bias supply which offers high power density for telecom, datacom and industrial power converter applications. It contains all of the features necessary to implement half-bridge topology power converters using voltage-mode control with input voltage feed-forward. This device is intended to operate on the primary side of an isolated DC-DC power converter with input voltage up to 100 V.

Features

  • High Integration Controller for Small Form Factor, High-Density DC-DC Power Converters
  • Integrated 100-V, 100-mA Auxiliary Bias Supply
  • Voltage-Mode Control with Input Voltage Feed-Forward
  • 100-V High-Voltage Start-Up Regulator
  • Fully Regulated Pre-Biased Start-Up
  • Enhanced Cycle-By-Cycle Current Limiting with Pulse Matching
  • Optimized Maximum Duty Cycle for Primary-Side FETs
  • Configurable Latch, OVP Operation
  • Integrated 100-V, 2-A MOSFET Drivers for Primary-Side FETs
  • Programmable Dead-Time Between Primary-Side and Synchronous Rectifier (SR) FETs
  • Create a Custom Design Using the LM5036 with the WEBENCH® Power Designer
