Maxim Integrated MAX8621ZETG+T Step-Down Converter

The MAX8621ZETG+T from Maxim Integrated is a high-performance, compact, and efficient step-down DC-DC converter designed for space-constrained applications. This advanced power management integrated circuit (PMIC) is ideal for portable devices where power efficiency and battery life are critical, such as smartphones, tablets, and other handheld devices.

Featuring a wide input voltage range from 2.6V to 5.5V, the MAX8621ZETG+T is capable of delivering an adjustable output voltage from 0.8V to VIN, which allows for flexible power supply design to meet the requirements of various low-voltage digital cores and peripherals. The device is capable of supplying up to 2A of continuous output current, ensuring sufficient power for demanding applications.

One of the key features of the MAX8621ZETG+T is its high efficiency, which is achieved through the use of an internal synchronous rectifier. This design minimizes power loss during the conversion process, thereby maximizing battery life. The converter operates at a fixed switching frequency of 2MHz, which allows the use of small, low-profile inductors and capacitors, further reducing the overall solution size.

The MAX8621ZETG+T is equipped with a range of protective features to ensure the reliability and longevity of the end application. These include overcurrent protection, thermal shutdown, and under-voltage lockout. Additionally, the device offers a low quiescent current, contributing to minimal power drain when the device is in standby mode.

This step-down converter comes in a compact, 24-pin thin QFN (4mm x 4mm) package, making it suitable for applications where board space is at a premium. The MAX8621ZETG+T also supports a complete power management solution with a minimal external component count, which simplifies design and accelerates time-to-market for product developers.

Overall, the Maxim Integrated MAX8621ZETG+T is a versatile and reliable choice for designers looking to improve power efficiency in their portable and space-constrained applications while maintaining high performance and robust protection features.
