NCP1011ST100T3G Description

Short technical summary and product information.

The ON Semiconductor NCP1011ST100T3G is a self-supplied monolithic switcher IC for low standby-power offline switch mode power supplies (SMPS). It integrates a fixed-frequency current-mode controller and a 700 V MOSFET, housed in a SOT-223 package.

 

This device features a 100kHz operating frequency, 19W power capability, and a 67% duty cycle. It supports a flyback topology with isolated output and includes essential fault protection mechanisms such as over load, over temperature, and over voltage protection. The internal switch is integrated, simplifying design.

 

The NCP1011ST100T3G operates within a voltage range of 8.5V to 10V and has an operating temperature range of -40°C to 150°C (TJ). It is supplied in a SOT-223 (TO-261) surface mount package.

 

This component is suitable for applications requiring rugged and low-cost power supplies, including low power AC/DC adapters for chargers and auxiliary power supplies for appliances and TVs.
