NCP1200P100G Description

Short technical summary and product information.

The NCP1200P100G from ON Semiconductor is a PWM current-mode controller specifically designed for low-power universal off-line power supplies. This device simplifies the design of reliable and cost-effective offline converters.

 

Key electrical specifications include a fixed operating frequency of 100kHz, a maximum operating voltage of 16V, and an 80% duty cycle. It supports flyback topology with isolated output and includes fault protection for current limiting, overload, and short circuits. The controller also features internal leading edge blanking and skip-cycle capability for improved efficiency at light loads.

 

Designed for ease of implementation, the NCP1200P100G does not require an auxiliary winding for operation. It is housed in a standard 8-PDIP through-hole package, making it suitable for various PCB mounting applications. The operating temperature range is from -25°C to 125°C (TJ).

 

This controller is suitable for applications such as AC-DC adapters, offline battery chargers, and auxiliary power supplies for appliances and TVs. Its features contribute to ultra-compact switchmode power supplies with minimal external components.
