Pin 8 (VREF) is the reference voltage output terminal. The output voltage of the pin is 5V and the output current can reach 5mA. This reference voltage can be used to power an external circuit.
8-pin package power chip TB6806, known as a low-power energy-saving power supply, it symbolizes the development direction of regulated power supply, has become the main product of regulated power supply. The chip has built-in loop compensation, eliminates additional compensation or filter capacitance, improves system efficiency, optimizes frequency reduction curve and reduces electromagnetic interference, and can realize light-load non-acoustic Multi-Mode control of primary side feedback control (PSR) constant current constant voltage (CC\/CV) controller efficiency to meet the six level energy efficiency requirements. Built-in 650V power MOSFET automatically compensates the input voltage. Inductance changes
Achieve multi-mode PSR control to improve reliability and efficiency Built-in soft start, low starting current, pin floating protection.
