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.主な特徴
- 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%
