NCP1203D60R2G Description

Short technical summary and product information.

The NCP1203D60R2G from On Semiconductor is a PWM current-mode controller specifically designed for universal off-line power supplies. It features an internal structure operating at a fixed 60 kHz switching frequency, making it suitable for compact switchmode power supplies.

 

This controller offers several key features including a high-voltage startup current source, auto-recovery internal output short-circuit protection, and extremely low no-load standby power. Its current-mode control provides inherent pulse-by-pulse control and adjustable skip-cycle capability for improved efficiency at light loads. The device operates within a voltage range of 7.8V to 16V and has a typical duty cycle of 80%.

 

Packaged in an 8-SOIC (Surface Mount) configuration, the NCP1203D60R2G is designed for ease of integration into various applications. Its operating temperature range is -40°C to 125°C (TJ), ensuring robustness in demanding environments. The controller includes protection against over load, over temperature, and short circuit conditions, with auto-recovery features.

 

This component is an excellent candidate for replacing older UC384X devices and is well-suited for AC-DC adapters, battery chargers, and auxiliary power supplies. It supports direct optocoupler connection and features internal leading edge blanking.
