MAX8620YETD+T

Overview

The MAX8620YETD+T is a synchronous step-down switching regulator manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for efficient power conversion in compact electronic systems. This component operates with an input voltage range of 2.7 V to 5.5 V and provides a fixed output voltage of 2.5 V at a maximum output current of 500 mA. It features a selectable switching frequency of either 2 MHz or 4 MHz, allowing for optimization between efficiency and external component size. The device incorporates a shutdown mode that reduces quiescent current to 10 nA, enhancing battery life in portable applications. With a typical static current of 28 uA during operation, it ensures high efficiency across varying load conditions. The regulator is housed in a small SC-70-6 package, suitable for space-constrained designs.

Feature Summary

• Synchronous buck topology for high-efficiency DC-DC conversion
• Dual selectable switching frequencies (2 MHz/4 MHz) for design flexibility
