udc3895 The difference is that the increased current in the PMP increases the feedback voltage but in the EVM the increased phototransistor current reduces the feedback voltage. Go to Support forums. Feb 5, 6: TI is a global semiconductor design and manufacturing company.

There is little difference between the two approaches.
