Overview

NCP1225 Product Preview Low Standby Power SMPS Controller NCP1225 is a low standby power Switch−Mode Power Supply, SMPS controller IC specially designed for low power AC−DC adapter applications.
The device operates in Discontinuous Conduction Mode (DCM) with Pulse Frequency Modulation (PFM) control scheme.
PFM operation can provide high operating efficiency even at light loading conditions and the device itself takes extremely low operating current.
With careful circuit design, low standby power down to 300 mW can be achieved for universal line input low power adapters.
This specific feature can help the end products to comply with immediate and future international power saving regulations ...
