The MAX619ESA+T is a switched capacitor voltage regulator/charge pump DC/DC converter, ideal for regulated, low cost, battery-powered applications, and as a voltage conversion device. This device from Analog Devices is a 2A, 5V voltage regulator and is designed to operate over a wide input range of 3V to 5.5V. It can also provide regulated output voltage when driven from a low input voltage, making it an ideal solution to ensure a steady voltage supply for single cell Li-Ion batteries. The MAX619ESA+T is designed with high efficiency to maximize battery life, low standby current, low output noise, short-circuit protection, and other advanced features. It is an easy-to-use device, requiring only two external capacitors with a total efficiency of up to 90%.
