CONDITION: V IN = 48V, I OUT = 3.1A
Summary
Using a high performance, low-cost PWM controller with a
low pin-count, outstanding performance has been achieved,
while keeping the cost to a minimum. The schematic and
BOM for both the versions are listed below. Other output
voltage versions are available upon request. Please contact
our Technical Support Center for custom output voltage
requirements. They can be reached through Intersil’s
website at http://www.intersil.com or via phone at 1-888-

4.15IN x 1.6IN
Test Procedure
Testing the Evaluation Board
? Connect the 3.3V load between the A3 (positive) and A4
(negative) terminals.
? Plug the cable coming from the PSE, carrying the input
voltage for the PD, into the Ethernet Jack J1.
? Measurements can be made on the 3.3V rail between pins
A3 and A4. For ripple and noise measurements, scope
probes with short ground leads must be used.
? Test Point A5 has been provided as the ground reference
of the primary circuit before the series-pass FET, Q1 is
turned on.
? In case of a Gigabit Network, T4 (included as part of the
Evaluation Kit) will have to be populated on the board, and
T3 removed. The rest of the procedure remains identical.
Testing the Power Train
? Connect the 3.3V load between the A3 (positive) and A4
(negative) terminals.
? Connect the DC power supply to the input terminals A1
(VDC) and A2 (Ground).
? Current-limit the DC power supply to about 0.5A, and turn
on the supply (36V - 57V DC).
? Measurements can be made on the 3.3V rail between pins
A3 and A4. For ripple and noise measurements, scope
probes with short ground leads must be used.
? Test Point A5 has been provided as the ground reference
of the primary circuit before the series-pass FET, Q1 is
turned on.
