General Description
The M62290L/FP is a general purpose DC/DC converter which provides 5.0 V fixed output.
It is possible to simplify peripheral circuits and to design compact and low cost sets because this IC includes a lot of
functions in small 5 or 8-pin packages.
Especially this is most suitable for a local voltage regulator of audio sets as a converter from 12 V to 5 V.
