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.

Current limit detection:
When the voltage drop between pin 3 and pin 4 becomes more than 140 mV, the current limit detection circuit
begins operating. The peak switch current "Ipk" is limited to 140 mV/RCLM. In the example of application
(Figure 1), the current is limited to 1.5 A.

7. With the exception of products specified by Renesas as suitable for automobile applications, Renesas products are not designed, manufactured or tested for applications
or otherwise in systems the failure or malfunction of which may cause a direct threat to human life or create a risk of human injury or which require especially high quality
and reliability such as safety systems, or equipment or systems for transportation and traffic, healthcare, combustion control, aerospace and aeronautics, nuclear power, or
undersea communication transmission. If you are considering the use of our products for such purposes, please contact a Renesas sales office beforehand. Renesas shall
have no liability for damages arising out of the uses set forth above.
8. Notwithstanding the preceding paragraph, you should not use Renesas products for the purposes listed below:
