AS1113, 13 W Powered Device (PD) with Integrated DC-DC Converter


AS1113 is a single-chip, highly-integrated CMOS solution for Power over Ethernet (PoE) applications

The AS1113 is a single-chip, highly-integrated CMOS solution for Power over Ethernet (PoE) applications that provide the world’s first seamless integration of Advanced Power Management, EMI Control, and High Voltage Protection in the industry's smallest and most cost-effective footprint.

The integration includes rectification and protection circuitry, a PD controller, and a DC-DC converter. This high level of integration provides faster response to surge events and limits stray surge current from passing through sensitive circuits, such as the Ethernet PHY device. The device is designed to provide a safe low-impedance discharge path directly back to the earth ground, resulting in superior reliability and circuit protection.

AS1113 has been architected and designed to address both EMI emission concerns and surge/over-voltage protection in PoE applications. The device implements many design features that minimize transmission of system common-mode noise onto the UTP cable.
