Overview

PMP7762 is an offline LED driver with TRIAC dimming. It has short circuit protection as well as op amp control for dimming. It uses 2 op amp control for each LED string to ensure that current in the LED strings match. LM3445 includes a bleeder circuit to ensure proper triac operation by allowing current flow while the line voltage is low to enable proper firing of the triac.
