Evaluation Board | NCP1075PSRGEVB

The NCP1075 Primary Sensed EVAL demo board is a universal input, off-line, 10 watt output, constant voltage power supply for powering E-meters or white goods applications where tight output voltage regulation is not necessary. This version of the NCP1075 flyback circuit does not have voltage sensing on the secondary side but utilizes the aux winding on the primary side of the transformer for sensing an analog of Vout, eliminating the use of an NCP431 andoptocoupler. For more information please see the datasheet.
