main feature

220V direct conversion, 3.3V5V, no inductor, low current power supply chip features High-precision output voltage, no power inductor, no input high-voltage capacitor, less device output 5V peripheral only 4 components, output 3.3V 3 components, output 2.7V 2 components, cost Low SOP-8 package, small PCBA size, optimized control method, improved efficiency, fast dynamic response and various protection functions: output short circuit protection, output undervoltage protection, output overload protection, built-in overheat protection

The AC input end of the AH8651 chip does not require commercial power to pass through the bridge, and does not require capacitor rectification. It can be AC110V120V220V direct conversion to 3.3V5V2.7V low current high withstand voltage offline, non-inductance AC input linear stabilized power supply chip simple circuit only need to adjust SEL Pin resistance value, AH8651 can obtain 5V/3.3V/2.7V output voltage. Simple and reliable offline power solution for obtaining bias power supply.

220V direct conversion, 3.3V5V without inductor, low current power supply chip self-recovery protection function: VDD undervoltage protection, VDD overvoltage protection, output overload protection, output undervoltage protection, lightning surge protection and built-in over temperature protection, etc.
