NCP1075STBT3G Description

Short technical summary and product information.

The ON Semiconductor NCP1075STBT3G is a current-mode PWM controller with an integrated 700V MOSFET, designed for low-power isolated flyback switched-mode power supply (SMPS) applications. It operates at a fixed frequency of 100 kHz and offers a maximum output power of 19 W at 230 Vac input.

 

This device integrates features such as soft-start, frequency jittering, short-circuit protection, and skip-cycle operation. It utilizes a dynamic self-supply (DSS) architecture, eliminating the need for an auxiliary winding, which reduces component count and simplifies circuit design. The NCP1075STBT3G provides protection features including overload, overvoltage, and short-circuit protection with auto-recovery.

 

Housed in a compact SOT-223 surface-mount package, the NCP1075STBT3G is suitable for space-constrained designs. Its low no-load standby power consumption, as low as 300 µA, makes it ideal for applications requiring high efficiency at light loads and reduced standby power.

 

Typical applications include auxiliary and standby power supplies for household appliances, set-top boxes, network routers, industrial control equipment, smart metering, and IoT devices.
