STEVAL-0608Y1V8 Evaluation Board

Introduction

The STMicroelectronics STEVAL-0608Y1V8 is a compact evaluation board for assessing a high-current step-down switching power supply design. Built around the DCP0608Y regulator, it converts a 5 V input supply into a regulated 1.8 V output capable of delivering up to 8 A.

Part Description

The STEVAL-0608Y1V8 is designed to demonstrate the performance, control features, and protection functions of the DCP0608Y synchronous buck regulator. Its programmed 1.8 V output makes it well suited for modern low-voltage digital loads that require substantial current from a 5 V power rail.

Key characteristics include:

• 5 V nominal input operation
• Input voltage support up to 6 V
• Fixed 1.8 V regulated output
• Output current capability up to 8 A
• 2.25 MHz switching frequency
