MAX619CSA Description

Short technical summary and product information.

The MAX619CSA from Analog Devices is a step-up charge pump DC-DC converter designed for portable and battery-powered applications. It provides a regulated 5V ±4% output at 50mA over temperature, with an input voltage range of 2V to 3.6V, suitable for two battery cells.

 

This converter operates with a 500kHz internal oscillator and requires minimal external components, fitting into a small 0.1in² board space. It uses only four external capacitors: two 0.22µF flying capacitors and 10µF capacitors at the input and output. The device features low operating supply current (150mA max) and a low shutdown supply current (1mA max), with the load disconnected from the input when shut down.

 

The MAX619CSA is available in an 8-pin SOIC package, making it ideal for space-constrained designs. Its charge pump topology eliminates the need for inductors, resulting in very low EMI noise. Applications include local 3V-to-5V conversion, 5V flash memory programmers, and regulated 5V supplies from lithium backup batteries.
