It is widely used in consumer electronics and industrial applications, such as common notebook adapter, small DC-DC converter, automotive applications and computer equipments, etc. This article will explore the basic application field and working principle of TCR2DG12,LF.

Application Field

TCR2DG12,LF voltage regulator can be applied in a variety of use cases. It can be used in common office equipment, such as laptop adapters and other power supply devices. It is also suitable for applications that require a precise control of output voltage, such as small DC-DC converters and motor control systems. It can also be used in automotive electronics, such as powertrains and engine control systems.

This device can also be applied in other applications which need precise voltage control, such as automated testing systems, medical equipment, and home automation. In addition, its small size and low noise design make it suitable for a variety of applications that require less space or minimal noise.

Working Principle

TCR2DG12,LF voltage regulator works by using linear regulation principle. It would start with controlling a reference voltage. This reference voltage will be compared to a feedback voltage which is proportional to output voltage, and a difference voltage between reference voltage and feedback voltage is created when the two signals are not the same. Then, the difference voltage will be amplified, and the amplified signal is then sent to control switch and send current to the output load.

The output voltage is regulated by the duty cycle of the switch. With the feedback voltage higher than reference voltage, the duty cycle of the switch will increase, and the output voltage will decrease; on the contrary, with the feedback voltage lower than reference voltage, the duty cycle of the switch will decrease, and the output voltage will increase. In this way, the output voltage can be regulated and stabilized.

Conclusion

TCR2DG12,LF is a voltage regulator with linear type for Power management integrated circuit (PMIC). This product provides the capability of low noise and adjustable output voltages up to 15V. It is widely used in consumer electronics and industrial applications, such as common notebook adapter, small DC-DC converter, automotive applications and computer equipments, etc. The output voltage regulated by TCR2DG12,LF is regulated by the duty cycle of the switch which is determined by comparing reference voltage with feedback voltage. In this way, the output voltage can be regulated and stabilized.
