FAN48630BUC33X application field and working principleThe FAN48630BUC33X is a synchronous buck PWM DC/DC voltage regulator from Fairchild Semiconductor. It is an ideal choice for applications that require the conversion of a wide input voltage range to a low, regulated output voltage. It requires minimal external components to achieve efficient voltage conversion when used as a standard buck regulator.The FAN48630BUC33X is available in a compact, thermally-enhanced QFN package, making it suitable for space-constrained applications. It offers a wide input voltage range from 4.5V to 17V, adjustable output voltages from 0.8V to 16V, a low quiescent current of only 5mA, and high efficiency output up to 95% over the entire input voltage range. Additionally, the part provides excellent transient performance with a fast transient response, low output voltage ripple, low EMI, and low noise operation.The FAN48630BUC33X is a DC/DC voltage regulator that uses Pulse Width Modulation (PWM) to switch an inductor between the input voltage source and the output voltage sink. This type of converter uses an inductor and a capacitor from the input voltage to the output voltage to store energy during the switching process. This energy is then moved between the input and the output as the output voltage is regulated. The PWM switching is controlled by an internal circuitry, allowing for highly accurate and stable output voltage regulation. This regulator is also equipped with many additional features such as soft-start, over-voltage protection, current limit protection, and thermal shutdown.The FAN48630BUC33X is an ideal solution for applications that require high efficiency, compact size, and low output voltage ripple. It is commonly used in consumer and industrial applications such as notebooks, digital still cameras, smartphones, workload processors, and communication equipment. Additionally, it is also suitable for green applications that require high efficiency, low standby current, and low noise operation.In summary, the FAN48630BUC33X synchronous buck PWM DC/DC voltage regulator from Fairchild Semiconductor provides high efficiency, small size, and excellent transient response for a wide range of applications. It requires minimal external components for efficient voltage conversion and is available in a thermally-enhanced QFN package. It is commonly used in consumer and industrial applications such as notebooks, digital still cameras, smartphones, workload processors, and communication equipment.
