The MAX619ESA+ from Analog Devices is a step-up charge pump DC-DC converter designed for battery-powered applications. It delivers a regulated 5V output with ±4% accuracy, capable of supplying up to 50mA when the input voltage is 3V or higher, and 20mA when the input is as low as 2V.
This device operates with an input voltage range of 2V to 3.6V, making it suitable for systems powered by two battery cells. It features an internal 500kHz oscillator and requires only four external capacitors, enabling an ultra-small application circuit occupying less than 0.1in². The low operating supply current (150mA max) and shutdown current (1mA max) further enhance its suitability for portable devices.
The MAX619ESA+ is available in an 8-pin SOIC package, designed for surface mounting. Its charge pump topology eliminates the need for inductors, resulting in very low EMI noise. The shutdown feature disconnects the load from the input when disabled, conserving power.
Applications include local 3V-to-5V conversion, 5V flash memory programmers, and regulated 5V supplies from lithium backup batteries.
