Infineon EiceDRIVER™ 2EDL90xG3 Gate Drivers

Introduction

Infineon Technologies’ EiceDRIVER™ 2EDL90xG3 family consists of 120 V gate drivers designed to support modern GaN and silicon power-switching designs. Built with a common footprint across the family, these devices provide a flexible solution for designers developing compact, efficient power-conversion and motor-control hardware.

Part Description

The 2EDL90xG3 is a gate-driver family featuring two completely floating output gate drivers. This architecture allows the devices to support several common switching arrangements, including dual low-side, dual high-side, and half-bridge configurations.

With support for both gallium nitride (GaN) and conventional silicon power devices, the family can be used across a range of switching topologies and power-system requirements. Its 120 V capability makes it well suited to low-voltage power stages where efficient, reliable gate control is important. The common-footprint approach can also simplify platform development by allowing compatible devices in the family to be evaluated or substituted without major PCB redesigns.

Applications

Potential applications for the EiceDRIVER™ 2EDL90xG3 include:

• Half-bridge power stages
• Synchronous buck converters
• Point-of-load power converters
• Low-voltage DC-DC converters
• Bidirectional DC-DC power stages
• Battery-powered power-management circuits
• Motor-drive inverter stages
