NCL2801CFADR2G Description

Short technical summary and product information.

The NCL2801CFADR2G from On Semiconductor is an 8-pin PFC controller IC designed to drive PFC boost stages. It utilizes an innovative Valley Count Frequency Fold-Back (VCFF) method, operating classically in Critical Conduction Mode (CrM) for high load values and transitioning to Discontinuous Conduction Mode (DCM) at lower loads to maximize efficiency.

 

This device offers near-unity power factor and features like fast line/load transient compensation, brown-out detection, and two-level line feed-forward. It supports a wide VCC range from 10.5V to 27V and provides high drive capability. The controller is housed in a compact 8-SOIC package, suitable for robust and space-efficient PFC stages.

 

Key electrical specifications include an operating voltage range of 10.5V to 27V and an output current capability of 800mA. The operating temperature range is -40°C to 125°C. The IC supports both Critical Conduction (CRM) and Discontinuous Conduction (DCM) operating modes, with a low start-up current consumption of 10 µA.

 

Applications for the NCL2801CFADR2G include PC power supplies, lighting ballasts (LED, fluorescent), flat TVs, and other off-line appliances requiring power factor correction. Its robust design and integrated features minimize external component count.
