Forward converter with Universal input driving 2x6 LEDs
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.
