However, there is a datasheet for the JW1981, which is a linear LED driver. After reverse-engineering the PCB, [bigclivedotcom] concluded that the JWB1981 must include an onboard bridge rectifier.

Diodes are essential semiconductor devices used to control the direction of electrical current in circuits. This tutorial explains how diodes work, their different types, and why they are critical ...
