Texas Instruments SN6505B | Demoboard UCC5390SCDEVM-010

Low-noise, 1-A, 420-kHz transformer driver with soft start for isolated power supplies

Overview

TopologyPush-Pull Converter symmetrical isolated
Input voltage3-5.5 V
IC revisionA

Description

The UCC5390SCDEVM-010 device is a complete, single-channel, isolated gate driver board with a reconfigurable bias supply, which provides a wide range of drive voltages. This EVM from TI is based on a 17-A, split output, basic insulation UCC5390SCD driver in a SOIC-8 package. The EVM also includes a SN6505B-based bias supply that can be configured for single or split-rail drive voltage from 11 V to 33 V,covering a wide range of Si and SiC FETs and IGBTs. Compact form factor, 1.5” × 0.83” × 0.3”, and embedded footprints for TO-220 and TO-247 power device packages, allow for easy, direct connection to FETs or IGBTs in the power system, for comprehensive performance evaluation.

Features

  • Compact, isolated gate driver board for direct connection to power FETs and IGBTs in high-voltage,mid-, and high-power converters and inverters
  • Split output, 17-A, typical sink and source drive current for optimal turn ON and turn OFF settings
  • Single or split rail bias supply configuration in 11-V to 33-V range
  • Robust, noise-immune solution with CMTI > 100 V per ns
  • Supports 3-kVrms basic isolation
  • Provides up to 0.8-W drive power using 80% efficient bias supply

Typical applications

  • Precision instruments, Process control
  • Medical instruments
  • Isolated power supply for CAN, RS-485, RS-422, RS-232, SPI, I2C, low-power LAN, Low-noise isolated USB supplies, Telecom supplies, Radio supplies, Distributed supplies, Low-noise filament supplies
