MITSUBISHI M62222L/FP 2.7V FIXED OUTPUT VOLTAGE DC-DC CONVERTER GENERAL DESCRIPTION M62222 is a general purpose DC-DC converter which provides a 2.7V fixed output voltage. It is possible to simplify the peripheral circuit and to design compact and low cost sets because this IC, housed in a small 5- or 8-pin package includes necessary peripheral components. Especially this is most suitable for CD-ROM, Disk Drive sets and PDA as a converter from 5V to 2.7V .
