Working Principle of the TK71750SIL

The TK71750SIL uses an open loop linear regulator to regulate the output voltage. It consists of a control circuit and a power circuit. The control circuit is used to adjust the voltage level of the output. It is powered by the VIN pin and its output is connected to the error amplifier. The error amplifier compares the output voltage with the reference voltage and provides the error signal to the control circuit.

The control circuit is responsible for compensating the output voltage in response to the error signal. The control output is connected to the power circuit, which consists of an adjustable load that is used to control the output current. The adjustable load maintains the output voltage at the set level by modulating the transconductor base current.

The TK71750SIL also features additional features such as protection circuitry and a shutdown mode. The protection functions include overvoltage protection, overcurrent protection, and short circuit protection. The shutdown mode can be used to shut down the TK71750SIL if the output voltage reaches a certain level.

Conclusion

The TK71750SIL is a combination of microcontroller and linear regulator which offers a wide range of application in industrial, medical, automotive, building automation and consumer markets. It is particularly suitable for applications that use harsh working conditions due to its extended temperature range. Its design also includes safety features such as overvoltage protection, overcurrent protection and short circuit protection.
