Multi-output, primary-side regulated flyback reference design for automotive IGBT gate drivers

Overview

TopologyFlyback Converter
Input voltage8-18 V
Output 18 V / 0.45 A
Output 215 V / 0.45 A

Description

This reference design provides an isolated power supply for automotive IGBT gate drivers. The primary-side regulated flyback controller LM25184-Q1 is used to avoid optocoupler and improve system reliability. Three transformers are used to achieve multiple outputs and facilitate flexible system layout.

Features

  • AEC-Q100-qualified for automotive applications
  • Device temperature grade 1: –40°C to 125°C ambient temperature range
  • Functional Safety-Capable
  • Documentation available to aid functional safety system design
  • Designed for reliable and rugged applications
  • Wide input voltage range of 4.5 V to 42 V
  • Robust solution with only one component crossing the isolation barrier
  • ±1.5% total output regulation accuracy
  • Optional VOUT temperature compensation - –40°C to +150°C junction temperature range
  • Integration reduces solution size and cost
  • Integrated 65-V, 0.11-Ω power MOSFET
  • No optocoupler or transformer auxiliary winding required for VOUT regulation
  • High-efficiency PSR flyback operation
  • Quasi-resonant MOSFET turnoff in BCM
  • Single- and multi-output implementations
  • Ultra-low conducted and radiated EMI signatures
  • Soft switching avoids diode reverse recovery
  • Optimized for CISPR 25 Class 5 requirement
  • Create a custom flyback regulator design using WEBENCH® Power Designer

Typical applications

  • Automotive IGBT gate drivers
  • Traction inverter: IGBT and SiC driver supplies
