Richtek RT9643 datasheet, stored as a 444 KB PDF. The RT9643 is a multi-output PWM controller with LDO used on notebook motherboards to produce standby and system rails such as 3.3 V and 5 V. Its pin description table and typical application circuit are useful when a board has no standby power, letting you check the input voltage, enable lines, power-good and switching nodes. Match the package and marking on the board before relying on the pin numbers given in the document.
