Datasheet for the L6738, an STMicroelectronics PWM controller for step-down converters, provided as a 773 KB PDF. Controllers of this type drive external MOSFETs to produce low-voltage rails such as memory or chipset supplies on motherboards and graphics cards. The document covers pin functions, typical application circuit, enable and power-good behaviour and feedback setup. Repair technicians use it to check supply and enable pins, measure the output against expected values and understand why a rail fails to start.
