SI34062-A-GM

Overview

The SI34062-A-GM is a Power Over Ethernet (PoE) Powered Device (PD) controller manufactured by Skyworks Solutions. It integrates an IEEE 802.3at compliant PoE interface with a DC-DC converter, designed for isolated Class 2 applications. The device operates within a supply voltage range of 2.7 V to 57 V and supports output configurations including 3.3 V and 5 V. It features integrated protection mechanisms such as transient overvoltage protection, thermal shutdown, and soft-start circuits. The component is housed in a 24-pin QFN EP package, suitable for compact surface-mount designs.

Feature Summary

• Integrates IEEE 802.3at compliant PoE interface with DC-DC conversion capabilities
• Includes internal transient surge suppression and thermal shutdown protection
• Supports isolated Class 2 power delivery architectures

Applications

• Isolated PoE powered devices requiring Class 2 compliance
