NCP1605BDR2G Description

Short technical summary and product information.

The ON Semiconductor NCP1605BDR2G is an integrated circuit designed for Power Factor Correction (PFC) applications. It operates in fixed frequency, Discontinuous Conduction Mode (DCM) or Critical Conduction Mode (CRM), exhibiting near-unity power factor.

 

Key features include a switching frequency up to 250 kHz, a wide VCC range of 10 V to 20 V, and high drive capability of -500 mA / +800 mA. The device integrates features for robust and compact PFC stages with minimal external components, including skip cycle capability for reduced standby losses.

 

This controller is housed in a 16-SOIC package and is suitable for surface mount applications. It offers safety features such as output under and overvoltage protection, brown-out detection, soft-start, overcurrent limitation, zero current detection, and thermal shutdown.

 

Typical applications include PC Power Supplies and all off-line appliances requiring power factor correction.
