Working Principle

The TES 5-1223 is a programmable step-up converter that uses a switching step-up topology. This type of topology is based on a pulse width modulation (PWM) control, and utilizes a pulse width modulator (PWM) to vary the duty cycle of the required output voltage. The PWM controller is used to drive a MOSFET that acts as a switch, allowing the current to flow through the inductor. A diode is used to provide reverse protection, and a voltage regulator is included to regulate the output voltage.The converter can be programmed to provide different output voltages depending on the requirement. A resistor divider is used to provide feedback to the PWM controller, allowing it to control the output voltage. The output voltage is programmed using external resistor dividers connected to the converter’s VFB and VDD pins. The VFB pin provides a fixed voltage reference that is used to compare the output voltage to, while the VDD pin is used to adjust the duty cycle of the PWM control. By connecting the appropriate resistors to the VFB and VDD pins, the user can program the output voltage from 0.95V to 5.1V.

Conclusion

The TES 5-1223 DC/DC converter is a versatile and robust device that can be used in a wide range of applications. It is capable of providing adjustable output voltages ranging from 0.95V to 5.1V, making it suitable for a variety of applications including automotive, industrial, and medical applications, as well as consumer electronics. The converter uses a switching step-up topology based on a pulse width modulation (PWM) control, and can be programmed to provide different output voltages depending on the requirement. Overall, the TES 5-1223 is an ideal solution for low voltage DC/DC conversion.
