DEMO MANUAL

DC981A/DC981B

LTC4263

Main Board, Single Port

Autonomous PSE/Daughter Card PSE

Description

Demonstration circuits 981A and 981B feature the

LTC

4263

in single port Power over Ethernet (PoE) power

sourcing equipment (PSE) midspan and endpoint solu-

tions. The LTC4263 is an autonomous single-channel PSE

controller for use in IEEE802.3af compliant PoE systems.

It includes an onboard planar power MOSFET, internal

inrush, current limit, and short-circuit control, powered

device (PD) detection and classification circuitry, and

selectable AC or DC disconnect sensing. Onboard control

algorithms provide complete PSE control operation without

the need of a microcontroller. The LTC4263 simplifies PSE

implementation, needing only a single 48V supply and a

small number of passive support components. Other op-

tions shown on the DC981A include legacy PD detection

enable, midspan backoff timer enable, power class enforce

mode, and power management enable. An LED for each

port is driven by the respective LTC4263 to indicate the

state of the port.

Quick start proceDure

Demonstration circuits 981A and 981B are easy to set

up to evaluate the performance of the LTC4263. Refer to

Figure 1 for proper measurement equipment setup and

follow the procedure below.

1. Place jumpers in the following positions:

JP1

JP2

JP3

JP4

JP5

JP6

DIS

2. Insert daughter card (DC981B) to main board

(DC981A) at polarized connector J3.

3. Apply 48V across VDD48 and VSS.

4. Connect a scope probe at VOUT_MD and VOUT_EP

both referenced to positive rail VDD48.

5. Connect a valid PD to either midspan PSE or

endpoint PSE.

6. Connect a second PD to the open port.
