NCP4326DR2 Description
NCP4326DR2, developed by ON Semiconductor, is a type of secondary controller embedded in the SOIC?16 package. It is capable of improving the overall efficiency and cross-regulation figures for multi?output voltage Quasi?resonant SMPS (switchmode power supplies) based on its individually regulating outputs. A precision reference voltage together with a dedicated operational amplifier is integrated to minimize the feedback loop elements. Its dedicated shutdown pins are able to disable the secondary outputs in applications requiring a low standby power performance.
