If you need help building out a full system schematic, tell me:
: A standard RCD snubber across the primary winding of the transformer is highly recommended to clamp the voltage spikes caused by transformer leakage inductance during MOSFET turn-off. Pinout Description (SOP8) Description CS : The device
: Features a multi-stage thermal foldback mechanism that lowers output current as temperatures rise, preventing absolute thermal failure.
