DER-715 is an evaluation board for a 24 W power supply designed for PC monitors. It features a 5V CV output and four independently regulated CC outputs for LED strings. The unique single-stage flyback architecture achieves 3% regulation on all outputs without the need for an additional DC-DC converter. This is only possible with PI's InnoMux2-BL switcher IC.
Please help me find out what is wrong with the circuit. The speaker can play sound when it is directly connected to the voice IC, but there is no sound after it is connected to the power amplifier. Th
