MP8017

IEEE 802.3af-Compliant PoE PD Solution

with Primary- or Secondary-Side Regulation

Active-Clamp Flyback Converter

DESCRIPTION

FEATURES

The MP8017 is an integrated, IEEE 802.3af-

compliant, power over Ethernet (PoE) powered

device (PD) with a flyback power converter. It is

targeted for small-sized, 13W, isolated PoE

applications.

•

IEEE 802.3af-Compliant

100V, 0.5Ω Powered Device (PD) Input

MOSFET

Active-Clamp Primary-Side Regulation

(PSR) Flyback without Auxiliary Winding

Active-Clamp Secondary-Side Regulation

(SSR) Flyback through Optocoupler

0.37Ω and 0.75Ω Integrated Flyback

MOSFETs

•

The PD interface has all the functions of IEEE

802.3af, including detection, classification,

inrush current limit, operation current limit, and

a 100V hot-swap MOSFET.

•

Configurable Frequency Up to 650kHz

1.5A Switching Current Limit

Output Diode Compensation in PSR Mode

Configurable Soft-Start Time

EMI Reduction with Frequency Dithering

Overload Protection (OLP), Over-Voltage

Protection (OVP), and Over-Temperature

Protection (OTP) with Hiccup Mode

Available in QFN-19 (3mmx4mm) Package

Optimized Performance with

The flyback converter is specifically designed

for active-clamp primary-side regulation (PSR)

flyback topologies. PSR provides a small-sized

solution. The MP8017 can also be set to a

secondary-side regulation (SSR) active-clamp

flyback topology. SSR optimizes regulation

through the optocoupler from the secondary

side.

•

The MP8017 can support a front-end solution

for PoE PD applications with a minimal number

of external components. It is available in a

QFN-19 (3mmx4mm) package.
