The NCL2801CDBDR2G from On Semiconductor is an 8-pin Power Factor Controller (PFC) designed for boost stages. It utilizes an innovative Valley Count Frequency Fold-back (VCFF) method, operating classically in Critical Conduction Mode (CrM) for high loads and switching to Discontinuous Conduction Mode (DCM) at lower loads to maximize efficiency.
This controller supports a wide operating voltage range of 10.5V to 27V and features a startup current of 10 µA. It offers near-unity power factor and includes features like Valley Turn-on, high drive capability (-500 mA / +800 mA), and a maximum switching period of 36.5 µs. The device is housed in a compact 8-SOIC package, suitable for robust PFC stages with minimal external components.
Key features include CrM and DCM operation, VCFF method for light load efficiency, and fast line/load transient compensation. Safety features such as thermal shutdown and over-voltage protection are also integrated. This makes the NCL2801CDBDR2G suitable for applications like PC power supplies, lighting ballasts, and other off-line appliances requiring power factor correction.
