Protection in LED opened condition
The operation with OVD terminal is available for the protection in case LED Circuit opened.
Please see the example of application circuit.
If load of LED is detached, Nch MOS switching operation is disabled with detection of boost circuit voltage.
Setting of external Capacitor
In case not using PWM signal to SHDN terminal for brightness control, recommended values are
C
1
= Over 2.2 (µF), C
2
= Over 1.0 (µF)
In case with PWM signal to SHDN terminal for brightness control, recommended values are
C
1
= Over 4.7 (µF), C
2
=Under 0.1 (µF) to reduce fluctuation of input current
and up accuracy of brightness.
The recommended capacitor values depend on the Brightness Control Method.
<Please see after page-8>
The capacitor value must be considered for gain enough accuracy of brightness with reduction of noise from
Input current changing.
Setting of I
