Product overview

Description

This document focuses on a reference design for a simple, low cost 12 V 1 A flyback converter based on the PM8800A device.

The PM8800A is a highly integrated device embedding an IEEE 802.3af compliant “Powered Device” (PD) interface together with a PWM controller.

It can be successfully used in all low power, low cost PoE applications.

  • All features

    • IEEE 802.3af compliant PD interface
    • Works with power supplied from Ethernet LAN cables or from local auxiliary sources
    • Line input voltage range: 40 Vdc to 60 Vdc Output voltage: 12 Vdc ± 5%
    • Output current: 1 A
    • Peak-to-peak output ripple: 100 mV
    • Efficiency DC-DC full-load: > 88%
    • Efficiency overall peak: > 85%
    • Transient response ΔVoutpk-pkto 50% load step: < 200 mVpp
    • ΔV in load line case: < 0.5%
