JWH7232 Overview
FEATURES The JW®H7232 is an integrate IEEE 802.3af PoE plaint Powered Device (PD), it includes PD interface and high efficiency flyback controller. The JWH7232 has all the functions of IEEE 802.3af, including detection, classification, power up inrush and operation current limit as well as a Hot-swap MOSFET. The DCDC converter uses primary-side regulation without opto-coupler feedback, simplifying the system design.
