Datasheet PDF for the OB2263, a current-mode PWM controller from On-Bright used in small offline switching power supplies and adapters. The 501 KB file provides the pin functions, typical application circuit, startup and protection characteristics. When repairing an adapter or LCD power board that will not start or hiccups, compare the VDD, gate and current-sense pin behaviour against the document. It also helps when checking the startup resistor and feedback loop components around the chip.
