This converter is designed for applications where isolation of the input and output is required. It has an operating temperature range of -40 °C to +85 °C, a minimum efficiency of 85%, and a maximum power output of 25W. The ITQ4805SA-H has a wide range of features that make it suitable for a variety of applications.

Application Fields

The ITQ4805SA-H is used in many different application fields, most notably in the automotive, industrial, and battery charging industries. In automotive applications, it is used to convert one DC voltage to another. The ITQ4805SA-H can be used to convert the 12V voltage from a car battery to the 6V voltage needed to power headlights or brake lights. In industrial applications, the ITQ4805SA-H can be used to regulate the voltage output from a generator to a level needed for power tools or other electrical devices. Finally, the ITQ4805SA-H can be used in battery chargers to convert an AC voltage to a DC voltage needed to charge a battery. This converter is also used in a variety of other applications such as solar power systems, RF communications, and even audio amplifier circuits.

Working Principle

The ITQ4805SA-H uses a buck-boost switching converter topology. A buck-boost converter is a type of DC-DC converter that takes a DC bus voltage as its input and outputs either a higher or lower voltage. The ITQ4805SA-H converter uses a switching topology, meaning that it uses a switch to periodically connect and disconnect the input and output of the converter. The frequency at which the switch operates is determined by the pulse width modulation (PWM) circuit that controls the converter.

The converter works by using two MOSFET switches that are connected in a half-bridge configuration. When the MOSFETs are turned on, current begins to flow from the input to the output of the converter. At the same time, the PWM circuit is turning the MOSFETs on and off at a rapid rate. This creates a pulse width modulated voltage at the output of the converter, which is then used to supply power to the load. The duty cycle of the PWM control can be adjusted to get the desired output voltage from the converter.

Conclusion

The ITQ4805SA-H is a high-efficiency DC-DC converter that is designed to be used in a variety of different applications. It is designed for use with input voltages from 4.5V to 5.5V and provides an output of 7V to 32V. It has a wide range of features and a high efficiency rating of 85%. The ITQ4805SA-H uses a buck-boost converter topology and works by turning two MOSFET switches on and off at a high frequency to generate the desired output voltage.

This converter is a popular choice in the automotive, industrial, and battery charging industries. It is used to convert one voltage to another or to regulate the output voltage from a generator. In addition, the ITQ4805SA-H is used in many other applications such as solar power systems, RF communications, and even audio amplifier circuits.
