Introduction to DC DC Converters

DC DC converters are electronic components that are used to change a DC voltage in one range to a different DC voltage in another range. They are also known as voltage convertors, DC to DC amplifiers and voltage modulators. They are widely used in industrial, automotive, power supplies, telecommunications, and consumer electronics applications.

CQHS3004832-R Application Field and Working Principle

The CQHS3004832-R is a monlithitic synchronous Buck DC/DC converter with integrated high and low side power MOSFETs. It provides a wide input voltage range of 8V-25V, adjustable output voltage range of 0.75V-16V, and a fixed switching frequency of 500KHz. It also features a wide range of current rating from 0.2A to 5A.The CQHS3004832-R is ideal for energy-efficient solutions requiring very low footprint. The high integration of the circuit components achieves a high efficiency and a low conductive dissipation. Additionally, the CQHS3004832-R has very low EMI noise, which is very beneficial in sensitive environments.The CQHS3004832-R can be used in a variety of applications such as distributed power, battery operated system, telecom/communications, automotive circuits, and computer/server circuitry.The basic operating principle of the CQHS3004832-R is to use the voltage difference between input and output to control the power-processing components. When the input voltage is higher than the output voltage, a power switch is triggered to transfer the power from the input to the output, thereby producing an output voltage from the same input voltage level. The power switch is typically a MOSFET, which is turned on or off to control the power transfer.When the voltage difference is small, a sensing circuit monitors the output voltage and adjusts the duty cycle of the power switch accordingly, thereby providing the regulated output voltage. The output voltage regulation accuracy is ±2.5%, with a typical ripple voltage of <50mV.

Conclusion

The CQHS3004832-R is a robust, small-footprint, and efficient DC/DC converter designed for a wide range of applications. Its wide input voltage and current range, regulated output voltage accuracy, and minimal ripple voltage make it an ideal choice for applications requiring high power efficiency and low EMI noise.
