Power passes through two N-channel MOSFETs (Check pins 1-3 for Source, pin 4 for Gate, and pins 5-8 for Drain). Primary Components (Top View) Let’s walk through a
You cannot directly parallel two LAC781P chips because the error amplifiers will conflict. Use the schematic top to understand why: each regulator tries to control its own output voltage, leading to one hogging all the current. Instead, use a single higher-current regulator or add ballast resistors.
