The ON Semiconductor NCP1012ST100T3G is a monolithic switcher for low standby-power offline Switch Mode Power Supplies (SMPS). It integrates a fixed-frequency current-mode controller with a 700V MOSFET, housed in a SOT-223 package.
This device offers features such as soft-start, frequency jittering, short-circuit protection, and skip-cycle operation for excellent light-load efficiency without acoustic noise. It supports Dynamic Self-Supply, eliminating the need for an auxiliary winding for basic operation. When an auxiliary winding is used, standby power can be reduced to less than 100 mW at high line, with built-in latched overvoltage protection.
Key electrical specifications include a maximum switching frequency of 110 kHz, an output current of 550 mA, and a maximum duty cycle of 72%. The operating supply voltage range is 8.5V to 10V, with a typical RDS(on) of 11 ohms. The operating temperature range is -40°C to 150°C.
Designed for ease of use, the NCP1012ST100T3G is suitable for applications like low power AC/DC adapters for chargers and auxiliary power supplies for appliances and TVs. Its surface mount SOT-223 package facilitates integration into compact designs.
