M62220L/FP
3.3V FIXED OUTPUT VOLTAGE DC-DC CONVERTER
GENERAL DESCRIPTION
The M62220 is a general purpose DC-DC converter which
provides a 3.3V 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 3.3V .
FEATURES
· Wide operation supply voltage range ·········· 4 to 15V
· Low power consumption ·········· 900µA(max.)
· Built-in oscillator without external components (110kHz 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
