Maxim Integrated MAX8625AETD+T Step-Down Converter

The MAX8625AETD+T from Maxim Integrated is a high-efficiency, compact, synchronous step-down DC-DC converter designed for a wide range of applications. This versatile component is ideal for portable devices due to its small size and efficiency, which help to extend battery life. With a 2.6V to 5.5V input voltage range, it can operate from a single Li+ cell, three NiMH cells, or a regulated 5V supply, making it a flexible choice for various power management tasks.

The MAX8625AETD+T features an adjustable output voltage from 0.8V to V<sub>IN, allowing for customization to meet the specific needs of the application. It can deliver up to 2A of output current, providing sufficient power for demanding tasks. The device's high switching frequency of up to 2MHz enables the use of small, low-cost capacitors and inductors, which is essential for space-constrained applications.

Efficiency is a key strength of the MAX8625AETD+T, with up to 96% peak efficiency. This is partially achieved through its low R<sub>DS(ON) internal switches, which reduce power loss while switching. Additionally, the device offers a 100% duty-cycle mode for low-dropout operation, ensuring consistent performance even when the input voltage is close to the output voltage.

The product incorporates several protective features to ensure reliable operation under various conditions. These include overtemperature protection, cycle-by-cycle current limit, and undervoltage lockout. The MAX8625AETD+T is also fully RoHS compliant, adhering to environmental standards that restrict the use of hazardous substances in electronic equipment.

Available in a compact 14-pin TDFN package, the MAX8625AETD+T is a space-saving solution that does not compromise on power or efficiency. Whether used in smartphones, tablets, wireless peripherals, or other portable electronics, this step-down converter from Maxim Integrated is engineered to meet the stringent requirements of modern power management designs.
