DC DC Converters

DC DC converters are essential components in modern electronics, allowing the power from one voltage system to be regulated and used for a different voltage system. The PAH50S48-3.3P/V is a DC DC converter that can offer both creative and reliable solutions to applications requiring two levels of power.

Application Field

The PAH50S48-3.3P/V is a high efficiency synchronous buck converter that is designed for applications where low output voltage regulation and good transient response are required. This converter provides up to 5 A of continuous current with up to 90% efficiency, allowing it to meet the needs of even the most energy-demanding applications. It features a wide operating voltage range of 3.5 V to 36 V, allowing it to be used to deliver regulated power to multiple devices such as LED drivers, FPGAs, microcontrollers, and ASICs. Furthermore, its low quiescent current of 5 µA makes it an ideal choice for applications requiring minimal dynamic power loss.

Working Principle

The PAH50S48-3.3P/V is a switching converter, meaning it works by rapidly switching between two states to regulate the output voltage. First, an adjustable current mirror is used to sense the output voltage and detect any irregularities. If an output voltage lower than the desired value is detected, the switching transistors are turned on, allowing current to flow from the input to the output. This operation serves to raise the output voltage back to the desired value. When the output voltage is too high, the switching transistors turn off, preventing current from passing from the input to the output. In this way, the PAH50S48-3.3P/V is able to continuously monitor and regulate the output voltage.

Conclusion

The PAH50S48-3.3P/V is a DC DC converter that offers creative and reliable solutions to applications requiring two levels of power. With a wide operating range of 3.5 V to 36 V, and up to 5 A of continuous output current, this converter is able to meet the needs of even the most energy-demanding applications. Its low quiescent current functionality further ensures minimal dynamic power loss. Through the use of its integrated adjustable current mirror, the PAH50S48-3.3P/V is able to continuously monitor and regulate the output voltage.
