DC-DC converters are electronic devices that are used to convert a DC voltage to another DC voltage, or from one voltage form to another voltage form. The device used in a DC-DC converter is covered by an integrated circuit, which is usually called a DC-DC converter. The most popular type of DC-DC converters are Step-Down (Buck) DC-DC Converters, which are used to reduce a high voltage to a lower voltage. The QSB30024S48 is a two-phase interleaved buck DC-DC converter that offers a low output voltage, high efficiency, low EMI, and a high power density.

Application Field

The QSB30024S48 has a wide application field due to its low output voltage and high efficiency. The device is suitable for a variety of industrial applications, such as automotive, industrial, and consumer applications. The device can operate at up to 3MHz switching frequency and can achieve up to 99.5% efficiency.

The QSB30024S48 is specifically designed for low-voltage applications, such as power supplies, consumer products, and distributed power systems. It is suitable for powering 1.5V, 1.8V, and 2.5V digital systems and a wide range of other voltage systems. It is also suitable for power management in low-power, portable applications.

Working Principle

The QSB30024S48 is an interleaved buck DC-DC converter that operates by switching between two phases. This type of converter offers a higher conversion efficiency compared to single-phase converters. The device is capable of operating at up to 3MHz switching frequency, which allows for faster power transfer. The two phases are interleaved, so that the output ripple voltage is minimized. The interleaved operation also ensures a high power density and high efficiency.

The QSB30024S48 uses an internal feedback loop to ensure that the output voltage is always accurately regulated. The device is configured to use either a voltage-mode or current-mode control loop to regulate the output voltage. This allows for precise regulation of the output voltage, even when there are sudden changes in the input voltage or load currents.

The QSB30024S48 offers a high power density and high efficiency due to the two-phase interleaved operation technology. The device has a low input current surge and low EMI due to its low switching frequency. The device also features a built-in over-temperature protection, which ensures that the device will not be damaged during a thermal overload.
