GENERAL DESCRIPTION
The MX841 features a 1.0MHz switching frequency to accommodate the use of small capacitors and a small inductor necessary in size sensitive portable applications. Light intensity and shutdown are conveniently controlled by a single analog voltage. Power efficiency and battery life are extended through the use of a high voltage, low RDSON Nchannel MOSFET switch. The MX841 is designed to operate over a temperature range of -40°C to +85°C, and is available in an SOIC-8 Package, with or without an Exposed Pad in Tube or on Tape and Reel. (Alternate package types available upon request).APPLICATIONS
