NCP1200D40R2G Description

Short technical summary and product information.

The NCP1200D40R2G from ON Semiconductor is a PWM Current-Mode Controller specifically designed for low-power universal off-line switching power supplies. This controller integrates features such as internal output short-circuit protection and skip-cycle capability for excellent light-load efficiency.

 

Key electrical specifications include a fixed operating frequency of 40kHz, with options for 60kHz and 100kHz available in other variants. It supports an 80% duty cycle and operates with a maximum voltage of 16V. The device is capable of 250 mA peak current source/sink. Its operating temperature range is -25°C to 125°C (TJ).

 

The controller is housed in an 8-SOIC package suitable for surface mounting. It offers no auxiliary winding operation and extremely low no-load standby power, making it ideal for compact and cost-effective AC-DC adapters and offline battery chargers. The current-mode control simplifies design and provides inherent pulse-by-pulse control.

 

This device is Pb-Free and Halogen Free, complying with RoHS standards. It is supplied in an 8-SOIC package with surface mount capability.
