Texas Instruments UCC35131EVM-118 Evaluation Module

Introduction

The Texas Instruments UCC35131EVM-118 is an evaluation module designed to help engineers assess the UCC35131-Q1 isolated gate driver bias power supply. It provides a practical platform for testing a compact, isolated power solution intended for demanding automotive and industrial electronics.

Part Description

The UCC35131EVM-118 demonstrates the operation and performance of the UCC35131-Q1 device, an isolated bias power supply designed for gate-driver applications. The module accepts an input voltage range of 5.5 V to 20 V and can deliver up to 2 W of output power.

A key characteristic of the board is its high isolation capability, rated at greater than 5 kVRMS. This makes it suitable for designs where low-voltage control circuitry must remain electrically isolated from high-voltage switching stages. Integrated protection features also support evaluation of fault-tolerant power-supply behavior in real-world operating conditions.

As an evaluation module, it is useful for examining startup behavior, regulation, efficiency, isolation requirements, output loading, and gate-driver bias supply performance before incorporating the underlying solution into a custom PCB.
