5.0V FIXED OUTPUT VOLTAGE DC-DC CONVERTER GENERAL DESCRIPTION
The M62290L/FP is a general purpose DC-DC converter which provides 5.0V 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 12V to 5V. PIN CONFIGURATION (TOP VIEW) 5 IN 4 VCC 3 CLM 2 GND 1 COLLECTOR Outline 5P5T
FEATURES
Wide operation voltage range ·········· 6 to 15 V (typ.Vcc=12V) Low power dissipation ··········1.1mA (max.,Vcc=12V) Built-in oscillator without peripheral devices (120KHz typ.) Built-in over current protection circuit Small 5-pin SIP and 8-pin SOP packages
