Description

M6227xGP is an integrated circuit designed as fixed output voltage general purpose DC/DC converter.

Integrating peripheral components in ultra small 5-pin SOT23 package allows for simplified external circuit and

compact low cost design.

This IC is applicable to portable equipments due to low circuit current 500

µA (typ.)

Especially this is most suitable for CD-ROM, and so on as converter from 5 to 3 V system.

Features

• Wide operation power supply voltage range…….. 4 V to 15 V (V

• Low power consumption………………………… 500 µA max. (V

• Built-in oscillator without peripheral components (110 kHz typ.)

• Built-in over current protection circuit

• Ultra small 5-pin SOT23 package

Applications

CD-ROM, portable equipments, general electric products
