Summary:
This document is an engineering report describing a 6.5 VDC, 600 mA CV / CC charger designed with the TNY266P.
The TNY266P chip consists of a 700V power MOSFET switch, a power controller and a protection circuit. The control method is different from the traditional PWM type switching power supply. It adopts simple on/off control output voltage, and the transient response time is faster than the traditional PWM type, and it has undervoltage protection function.
This document includes power specifications, circuit diagrams, bill of materials, transformer specifications, printed circuit board layout, design spreadsheets, and performance data.
