It includes the following aspects: 1. VCC pin: Input power voltage.
2. GND pin: Ground.
3. FAULT pin: Outputs an error signal. When a FAULT occurs such as the chip temperature is too high, the fault pin will output a high level signal.
4.D pin: switch tube drive output.
5. S pin: MOS field effect tube drain. 6. CS pin: electric fluidometer, used to achieve overload protection and constant current output control.
7.FB pin: Feedback control, according to the difference between the output voltage and the reference voltage to control the output voltage value. In summary, the pin functions of the tny 267 power chip are very rich, and can achieve a variety of protection and control functions, which has high practical value.
1, TN267 power chip has 5 pins, including VIN, VOUT, GND, EN, FB. Where VIN is the input voltage, VOUT is the output voltage, GND is the ground end, EN is the enable end, FB is the feedback end. VIN and VOUT are the main power pins, EN for high power level chip work, otherwise stop; The FB pin is used to control the power output voltage.
3, TN267 power chip is an energy-efficient DC-DC step-down chip, through the use of PWM technology, as well as complex circuit control, to adjust and control the output voltage to ensure the stability and efficiency of the circuit.
For this matter, TNy267 is a low-voltage differential linear regulator with the following pin functions:
1. Input (VIN) : Connect the power input. Electrolytic capacitor filtering is recommended.
2. GND: Connects the ground cable.
3. Output (VOUT) : Connect the load, it is recommended to use electrolytic capacitor filtering.
4. Adjust (ADJ) : Connect the adjusting resistor to adjust the output voltage.
5. Power control (EN) : Connect the power control signal, the high level is effective.
6. Overheat protection (SHDN) : Connect the overheat protection signal, the high level is effective.
Hello, as there is no specific model information, we cannot determine the pin function of the TNY 267 power chip. The pin function of different models of chips may also be different, and you need to check the relevant data manual or data sheet to determine. It is recommended that you provide more specific model information or consult the relevant data manual.
