    Hi Hsu cheng,

    TPS23861EVM-612 should be a good reference as it has 2 TPS23861 ICs on the board. TPS23882(8 channel 30W PSE) has been just released on TI.com and this is better for your customer's 16 port system. With TPS23882, less external components are needed and less software effort is needed (no need to program I2C address through software, TPS23882 uses hardware pins to program the address). Please refer to TPS23882EVM-084 for the hardware design. In addition, if your customer needs software to control the PSE system (multi power supplies, port power management, etc), we also offer full system software solution(We call it FirmPSE and the software is written in MSP430F5234). Please go to TPS23882EVM-084 folder and request access to FirmPSE mySecure folder. Thanks.

    Best regards,

    Penny
