General Description
The M62221 is a general purpose DC/DC converter which provides a 3.0 V 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 5 V to 3.0 V.
Features
• Wide operation supply voltage range…...4 to 15 V
• Low power consumption………………..900 µA (max.)
• Built-in oscillator without external components (110 kHz typ.)
• Built-in over current protection circuit
• Small size 5-pin SIP and 8-pin SOP packages
Applications
CD-ROM, PDA, general purpose electric products
