M62221L/FP
3.0V FIXED OUTPUT VOLTAGE DC-DC CONVERTER
April. 1997
( 3 / 3 )
Application Circuit (3.0V Output DC-DC Converter)
Current Limit Detection:
When the voltage drop between pin 3 and pin 4 becomes more than 150mV,
the Current Limit Detection circuit begins operating. The peak switch
current "Ipk" is limited to 150mV / R
CLM
. In the example of application
(fig.1), the current is limited to 1.5A.

THE EXPRESSION OF CIRCUIT CONSTANTS
VF :Forward voltage drop of an external diode.
Vsat :Output saturation voltage of an external switching transistor.
I
O
:It should be set between 1/3 and 1/5 of maximum output current.
An external transistor, diode and inductor should have a peak current capability of
greater than "Ipk".
