Overview

PMP7755 is a non-synchronous buck controller for LM3409 with 24V DC input and 18V output @ 4.2A. The load is 9 strings with 6 LEDs per string. It uses a motion detector with PIR (passive infarared) dimming as well as 0-10V analog dimming. It has differential high side current sensing which enables setting the dimpoint on PIR. It also has a turn on/off delay.
