Working Principle

The TCV7100AF(TE12L,Q) DC DC Switching Regulator uses a synchronous buck converter topology to step-down or step-up the input voltage. It has two main components, the driver circuit and the secondary part of the switching regulator. The driver circuitexamines the output voltage through a feedback network to adjust the duty cycle to regulate the output voltage. When the output voltage is low, the duty cycle is increased to boost the output voltage and vice versa. In order to ensure a stable and noise-free output voltage, the driver circuit monitors the output voltage and compensates the duty cycle in order to maintain a steady output voltage.The secondary part is responsible for switching the current to the load. It consists of an integrated power switch, an inductor, and a diode. The driver circuit controls the switching of the primary switch according to the output voltage. The primary switch conducts when a high voltage is applied to the gate and it is turned off when the voltage drops below a certain value. The inductor stores the energy during the high side of the switching while the diode reverse biases the current when the low side of the cycle is present.When the primary switch turns off, the energy stored in the inductor is transferred to the load and the output voltage is regulated by adjusting the duty cycle.

Conclusion

The TCV7100AF(TE12L,Q) DC DC Switching Regulator is an advanced regulator with a wide range of features and functions that make it suitable for numerous applications. It is designed to offer high efficiency and low noise and offers excellent performance with an adjustable output voltage range of 0.6V to 36V and maximum output current of 40A. The regulation is achieved by a synchronous buck converter topology that adjusts the duty cycle to maintain a stable output voltage.
