NCP1622AEASNT1G Description

Short technical summary and product information.

The NCP1622AEASNT1G 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 it to operate efficiently at both nominal and light loads by reducing standby losses. This controller classically operates in Critical Conduction Mode (CrM) when the control voltage exceeds a programmable value, and linearly decays frequency down to approximately 30 kHz at lower control voltages.

 

Key features include near-unity power factor, on-time modulation for proper 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. The device operates within a VCC range of 9.5 V to 30 V and has an operating temperature range of -40°C to 125°C (TJ).

 

Housed in a compact 6-TSOP package (SOT-23-6 Thin, TSOT-23-6), the NCP1622AEASNT1G requires few external components, making it suitable for robust and compact PFC stages. Its typical applications include PC power supplies, lighting ballasts (LED, Fluorescent), flat TVs, and other offline appliances requiring power factor correction.
