Introduction

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

The UCC5390SCDEVM-010 device uses a 17-A, split output driver, UCC5390SCD, and an SN6505B-

based bias supply. The EVM can be configured with or without split rail, for optimal drive voltages

depending on the specific application. By default, the bias supply is configured as a split-rail supply

providing 18-V turn ON and –4-V turn OFF, which is optimal for many SiC FETs.
