M62290L/FP 5.0 V Fixed Output Voltage DC/DC Converter REJ03D0850-0300 Rev.3.00 Jun 15, 2007 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. Features • • • • • Wide operation voltage range: 6 to 15 V (typ. VCC = 12 V) Low power dissipation: 1.1 mA (max., VCC = 12 V) Built-in oscillator without peripheral devices (120 kHz typ.)
