Texas Instruments LM5180 | Demoboard PMP30629
Isolated 2.5-W SiC & IGBT gate-drive reference design with integrated switch PSR flyback converter
Overview
| Topology | Flyback Converter |
| Input voltage | 9-36 V |
| Switching frequency | 12-350 kHz |
| Output 1 | 15 V / 0.13 A |
| Output 2 | -4 V / 0.13 A |
| IC revision | B |
Description
This document analyzes two methods to increase the drive current from integrated gate-driver ICs. The performance of both the methods is compared by building boards and testing them at various conditions.These circuits are discussed in further detail in subsequent sections.
Features
- Designed for reliable and rugged applications– Wide input voltage range of 4.5 V to 65 V– Robust solution with only one component crossing the isolation barrier– ±1.5% total output regulation accuracy– Optional VOUT temperature compensation– 6-ms internal or programmable soft start– Input UVLO and thermal shutdown protection– Hiccup-mode overcurrent fault protection– –40°C to +150°C junction temperature range
Typical applications
- Multi-output rails for analog input modules
- Motor drive: IGBT gate drive supplies
- Building automation HVAC systems
- Isolated field transmitters and field actuators
