Richtek marking-code reference in PDF format. Richtek power ICs, including PWM controllers, buck converters, LDOs and load switches, are very common on laptop motherboards and graphics cards, and their small packages carry only short codes. Looking up that code here gives the part number, after which the datasheet shows pinout and operating details for checking rails or ordering a replacement. Codes can repeat across packages and date batches, so match the package outline as well before relying on an identification.
