NCP1622BECSNT1G Description

Short technical summary and product information.

The NCP1622BECSNT1G from ON Semiconductor is an enhanced, high-efficiency Power Factor Controller designed to drive PFC boost stages. It utilizes an innovative Valley Synchronized Frequency Fold-back (VSFF) method, allowing for efficient operation in Critical Conduction Mode (CrM) at nominal loads and reduced frequency operation at light loads to minimize standby losses.

 

This controller supports a wide VCC range from 9.5 V to 30 V and operates within a temperature range of -40°C to 125°C. Key features include near-unity power factor, on-time modulation for current shaping in VSFF mode, and skip mode at very low load currents. It also incorporates a dynamic response enhancer for fast line/load transient compensation and valley turn-on.

 

Housed in a compact 6-TSOP package, the NCP1622BECSNT1G is suitable for robust and compact PFC stages with minimal external components. Its safety features include thermal shutdown, over-voltage protection, brown-out detection, and over-current limitation.

 

Typical applications for this device include PC power supplies, lighting ballasts (LED, fluorescent), flat TVs, and other offline appliances requiring power factor correction.
