DC DC converters form the backbone of the power electronics industry. DC DC converters transform electrical energy from one voltage level to another. In this article, we discuss the application field and working principle of ULTVT006A0X3-SRZ DC DC converter.

Application Field

ULTVT006A0X3-SRZ DC DC converter is a high performance, low cost (< $100 USD) converter that is suitable for applications such as distributed power architectures (DPA), in which multiple voltage rails are used to power a variety of devices. ULTVT006A0X3-SRZ is ideal for supplying power to industrial and commercial applications, and has been successfully used in the automotive, medical, aviation and defense industries.

ULTVT006A0X3-SRZ offers a wide input voltage range of between 6-18Vdc, making it suitable for most applications. It has an adjustable output voltage of up to 5Vdc and is short-circuit proof. The efficiency of this model is up to 92% with a wide temperature operating range of -40 to 85°C. ULTVT006A0X3-SRZ is also RoHS compliant and has UL94V-0 approved plastic package.

Working Principle

ULTVT006A0X3-SRZ DC DC converter is a buck-type converter, which works by switching the input voltage at a frequency of 300kHz. When the switch is turned on, electric energy is stored in the inductor. During this time, the output voltage is also increasing gradually. When the switch is turned off, the stored energy is discharged to the load and current flows through the diode. This creates an output voltage that is equal to the input voltage minus the voltage drop across the switch and the diode. The switching frequency is controlled by the on-board oscillator, while the output voltage is adjustable using the onboard potentiometer.

The ULTVT006A0X3-SRZ utilizes a voltage mode control method to ensure precise and stable control of the output voltage. The converter is equipped with an internal voltage reference that provides a stable reference voltage to the error amplifier. The error amplifier compares the reference voltage with the output voltage to obtain the error voltage. This error voltage is then used to adjust the duty cycle of the switch. If the output voltage is too high, the duty cycle of the switch is decreased; if the output voltage is too low, the duty cycle of the switch is increased.

Conclusion

ULTVT006A0X3-SRZ is a DC DC converter with wide operating range, high efficiency and low cost that is suitable for a range of applications. This converter is a buck-type converter and uses voltage mode control to ensure precise and stable control of the output voltage. The ULTVT006A0X3-SRZ has been successfully used in a variety of industries and is an excellent choice for distributed power architectures.
