The ATH016A0X3 is a DC to DC converter that combines several essential functions in one package, including voltage regulation, current regulation, and temperature protection. This article covers ATH016A0X3 application field and working principle.

Application Field of ATH016A0X3

The ATH016A0X3 DC-DC converter has a wide range of applications. It can be used in different electronic circuits, such as charge controllers, battery chargers, LED lighting, solar energy harvesting, automotive electronics, and many other DC circuits. Specifically, this DC to DC converter is suitable for applications where power efficiency is a crucial factor. It has an efficiency of up to 95%, making it highly efficient at saving energy that could otherwise be wasted, as well as reducing power dissipation and heat generation.

The ATH016A0X3 DC-DC converter features a wide input voltage range from 6 to 25V, adjustable output voltage from 1.2 to 14V, maximum output current of 6A, and high efficiency of up to 95%. It also has several protection features, including UVLO protection, short circuit protection, and over-temperature protection. All of these features make the ATH016A0X3 well-suited for a variety of DC regulated power supply applications.

Working Principle of ATH016A0X3

The ATH016A0X3 DC-DC converter is a three-terminal integrated switching regulator. It combines an adjustable voltage regulator with a high side MOSFET and a low side MOSFET and a controlled switch in a single package, making it ideal for applications where power and space savings are important. The ATH016A0X3 uses an external transistor and MOSFET to convert the input voltage to the desired output voltage.

The ATH016A0X3 utilizes Pulse Width Modulation (PWM) to regulate the output voltage. The PWM is generated by a voltage reference connected to the converter\'s feedback terminal. The feedback voltage is compared with the output voltage in order to adjust the duty cycle. As the output voltage deviates from setpoint, the duty cycle increases or decreases and the output voltage follows.

The converter\'s output voltage and current are controlled by the on-board voltage reference and sensors. The output current is limited by sensing the voltage across a current sense resistor. This sensing voltage is also used to provide over-current protection. The output voltage is also monitored, and the over-temperature protection is based on the temperature detected by its internal temperature sensing diode.

Conclusion

The ATH016A0X3 DC-DC converter is a highly efficient device with a wide input voltage range, adjustable output voltage, and high efficiency. The converter combines several essential functions with comprehensive protection features, making it ideal for a variety of DC regulated power supply applications. The ATH016A0X3 utilizes Pulse Width Modulation to regulate its output voltage, and its output current and voltage are controlled by on-board voltage references and sensors.
