NCP1015ST65T3G Description

Short technical summary and product information.

The NCP1015ST65T3G from ON Semiconductor is a self-supplied monolithic switcher for low standby-power offline Switched-Mode Power Supplies (SMPS). It integrates a fixed-frequency current-mode controller with a 700V voltage MOSFET, housed in a SOT-223 package.

 

This device operates at a fixed frequency between 65 kHz and 100 kHz, with skip-cycle operation at low peak currents to minimize acoustic noise and improve light-load efficiency. Key features include internal soft-start, auto-recovery output short-circuit protection, and frequency jittering for better EMI performance. The integrated 700V MOSFET has a typical RDS(on) of 11 Ω.

 

Designed for rugged and low-cost power supplies, the NCP1015ST65T3G is suitable for applications such as low-power AC-DC adapters for chargers and auxiliary power supplies for appliances and TVs. It offers a maximum output power of 19 W at 230 Vac.

 

The component is surface-mountable in a SOT-223 (TO-261) package. It operates within a temperature range of -40°C to 150°C (TJ) and has a duty cycle of 67%.
