NCP1075PSRGEVB: Primary-Side Controlled, 10-Watt, Offline Flyback Evaluation Board

NCP1075PSRGEVB: Primary Side Controlled, 10 Watt, Off-line Flyback Evaluation Board

Overview

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 and
optocoupler. For more information please see the datasheet.

Some issues with "battery balancing"
[size=4] "Battery balancing" is not a new term. It has been used on nickel-cadmium batteries for at least 30 years. It's just that the early technology was simple and inefficient. Its principle and me
How do you know if an 8-bit microcontroller is enough?
I made a pressure tester that needs to display 20000HPA. The unit must be HPA, and the output rate must not be less than 10KHZ.
