onsemi power IC NCP1014ST100T3G Offline SMPS IC High-voltage PWM controller
The NCP1014ST100T3G is a high-voltage, monolithic switching regulator from ON Semiconductor, designed for low-power offline SMPS (Switched-Mode Power Supply) applications. This PWM (Pulse-Width Modulation) controller integrates a 700V avalanche-rugged power MOSFET, enabling efficient power conversion in AC-DC adapters, auxiliary power supplies, and LED drivers. Operating with a fixed switching frequency of 100 kHz, it provides stable performance while minimizing external component count, making it ideal for cost-sensitive designs. The device supports a wide input voltage range (85V to 265V AC), ensuring compatibility with global mains standards.
TheNCP1014ST100T3G features built-in soft-start to reduce inrush current, enhancing system reliability during startup. Its auto-restart protection mechanism safeguards against overload, short-circuit, and open-loop conditions, preventing damage to the power supply. With low standby power consumption (<100 mW), the IC complies with energy efficiency standards such as ENERGY STAR and EU CoC. The current-mode control architecture ensures excellent line and load regulation, while the high-voltage startup circuit eliminates the need for an external bias supply, simplifying PCB design.
Housed in a SOT-223 package, the NCP1014ST100T3G offers compact thermal management and is suitable for space-constrained applications. It provides up to 12W of output power in isolated flyback configurations, making it a versatile choice for consumer electronics, IoT devices, and industrial control systems. The device operates over an industrial temperature range (-40°C to +125°C), ensuring robust performance in harsh environments.
