DC DC Converters
A DC-DC converter is an electronic circuit which converts a source of direct current (DC) from one voltage level to another. It is a type of electric power converter. DC-DC converter is used for multiple levels of fixed output voltage or a continuously adjustable level of output voltage. By using it effectively, it can help devices run smoother and more efficiently.
The PAQ100S481R8/B is one type of DC-DC converter which is designed for applications that need highly reliable and energy-saving power supply. It is compact sized, with surface-mount form factor. PAQ100S481R8/B is able to do AC/DC input from 100V – 240V and provide a DC output voltage of either 5V, 12V or 24V output pin. It can control the output voltage with ±5% load regulation and an additional ±2% load stabilization effectiveness.
The working principle of PAQ100S481R8/B is based on a concept known as buck-boost. It is a type of DC-DC converter which uses both the inductor and a capacitor to "boost" the voltage or "buck" the voltage, depending on the desired polarity. Buck-boost converters are generally used in cases where the input voltage can exceed, be lower, or be higher than the output voltage. In this case, the PAQ100S481R8/B input AC/DC voltage wraps around an inductor before entering the capacitor. Then the input passes to a diode and a transistor that control the output voltage.
The PAQ100S481R8/B is mainly used in automotive electronics, small portable electronic systems, home appliances, consumer electronics and power banks. Besides, it can also be used in applications like solar power generation systems, telecom systems, or switching mode power supplies (SMPS).
The main advantage of PAQ100S481R8/B over traditional transformer-based power supplies is its improved efficiency. These type of power supplies don’t need to ‘step up’ or ‘step down’ the voltage and thus eliminates additional losses due to the effectiveness of the transformer. Hence, it is very suitable for applications that require an energy-saving power supply.
