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. V_CC = 12 V)
• Low power dissipation: 1.1 mA (max., V_CC = 12 V)
• Built-in oscillator without peripheral devices (120 kHz typ.)
• Built-in over current protection circuit
• Small 5-pin SIP and 8-pin SOP packages
Applications
Local voltage regulator of audio sets and general electric products
