NCP1611BDR2G Description

Short technical summary and product information.

The NCP1611BDR2G from ON Semiconductor is an advanced power factor controller designed for high-efficiency PFC boost stages. It utilizes an innovative Current Controlled Frequency Fold-back (CCFF) method, operating in Critical Conduction Mode (CrM) at higher currents and linearly decaying frequency down to 20 kHz at low currents. This ensures maximum efficiency at both nominal and light loads, significantly reducing standby losses.

 

This IC allows for near-unity power factor even with reduced switching frequencies, making it suitable for compact PFC stages with minimal external components. It features a wide operating voltage range of 9.5V to 35V and an operating temperature range of -40°C to 125°C. The device is housed in a standard 8-SOIC package and supports surface mount installation.

 

Key features include skip mode near line zero crossing, fast line/load transient compensation, and valley turn-on. It also incorporates safety features such as over-voltage protection, brown-out detection, and thermal shutdown. The NCP1611BDR2G is configurable for low harmonic content and is EN61000-3-2 Class C compliant for dimmable light ballasts.
