Datasheet for the Richtek RT8239A, provided as a 404 KB PDF. Richtek RT82xx parts are commonly used on laptop boards as dual-output PWM controllers that generate the 3V and 5V system and standby rails. The datasheet gives the pinout, typical application circuit, enable and power-good behaviour and electrical ratings. A technician uses it to check which pins should carry voltage, measure feedback and switching nodes, and decide whether the controller or its MOSFETs failed when a board shows no standby power.
