MAX859 - Step-Up DC-DC Converters

Download the MAX859 datasheet PDF. This datasheet also covers the MAX858 variant, as both devices belong to the same step-up dc-dc converters family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX856

MAX859 are high-efficiency, CMOS, stepup, DC-DC switching regulators for small, low input volt age or battery-powered systems.

The MAX856/MAX858 accept a positive input voltage between 0.8V and V OUT and convert it to a higher, pin-selectable output voltage of 3.3V or 5V.
