AZ494CUP-E1 is a DC-to-DC switching regulator created by Ricoh Company and designed specifically for providing power to a variety of smaller electronic devices including cell phones, portable media players, digital cameras, and other similar devices. It is part of the voltage regulators group of products from Ricoh, categorized as DC-DC Switching Regulators. This regulator is ideal for applications where efficiency, size, and cost are important considerations as it does not require a large number of components and can fit in applications that have limited board space.

This particular regulator is capable of delivering up to 1A continuous output current and up to 2.5A peak current for the output voltage range of 0.4V-4.4V with a resolution of 10mV and an adjustable output voltage accuracy of ±2%. The AZ494CUP-E1 is a 4-pin IC, with a small footprint that measures only 5mm. It is packaged in a 5-times-5mm QFN-24 package, making it suitable for handheld devices.

The AZ494CUP-E1 implements both synchronous and non-synchronous operations, depending on the application’s requirements. In synchronous operation, the switching frequency can be configured between 200kHz and 1MHz, and the output voltage can vary up to ±1%. Non-synchronous operation uses a fixed frequency of 350kHz and allows the output voltage to be adjusted up to ±2%.

The AZ494CUP-E1 also has a number of safety and protection features, providing protection against output over-voltage, current-limit, thermal overload and short-circuit. In addition, the device has an auto-restart feature for when the thermal protection circuit is triggered.

The AZ494CUP-E1 is a versatile and reliable solution for powering handheld equipment such as mobile phones, media players and other types of small electronics. It is a cost-effective solution with low component count and simple implementation, making it suitable for applications with limited board space. The adjustable output voltage and high efficiency make it suitable for a variety of applications, and the safety features ensure that the device is protected in the event of any faults.

The AZ494CUP-E1 is an ideal voltage regulator for applications requiring small size, low cost and high efficiency. It is easy to implement and offers a variety of features including adjustable output voltage, current-limit protection, thermal overload protection and short-circuit protection. The device can be used in a variety of applications, including portable electronic devices, media players and other types of small electronics.
