Product Number: LTC4263
Dear All,
I'm planning to use LTC4263IDE#PBF for IEEE802.3af Class2 power management.
I plan to use 4 circuits in parallel. Referring to Figure 5 on the datasheet, I connected all the PWRMGT pins, set RPM to 7.68kΩ, and CPM to 1uF.
As a result, PoE power is supplied for one device, but when four devices are connected, only one is powered.
Using the RPM formula, I calculated 7.68kΩ as 213kΩ/(7W×4).
Is this wrong?
As additional information, the PoE classification waveform is Class2, 15.6V. If anyone has any information, please reply.
