The ON Semiconductor NCV1362ABDR2G is a high performance primary side PWM controller for low power offline switching power supplies (SMPS). This device provides improved power efficiency, reduced external components, low component count, and low cost. It features a wide voltage range of operation, a programmable high-voltage start up, and robust protection features. The NCV1362 integrates an independent high-voltage start up section that can be used to set the output voltage of the isolated SMPS. The integrated regulated start-up power circuitry eliminates the need for an external start-up resistor. Its protection features include hysteretic line OVP (Over Voltage Protection), line UVLO (Under Voltage Lock Out), and adjustable soft start. It is packaged in a small, 8-lead SOIC (Small Outline Integrated Circuit) package.
