IEEE 802.3af PD Interface and PWM Controllers

with Integrated Power MOSFETs

Layout Recommendations

All connections carrying pulsed currents must be very

short, as wide as possible, and have a ground plane as

a return path. The inductance of these connections

must be kept to a minimum due to the high di/dt of the

currents in high-frequency-switching power converters.

Current loops must be analyzed in any layout pro-

posed, and the internal area kept to a minimum to

reduce radiated EMI. Ground planes must be kept as

intact as possible.
