Function explanation
1
K
It is the connection terminal with cathode and IF setup resistance of
LED. It is the feedback terminal of the charge voltage wave form for the
LED current control.
It is the ground terminal of the logic part.
2, 5
GND
3
SHDN
It is the enable terminal. It becomes the standby mode with "L", and the
LED is turned off. The lighting operation is given with "H".
4
Vcc
It is the input terminal of the operation voltage for the IC. The operating
voltage is 3.0 to 5.5V.
It is the switch terminal of the coil for the DC/DC converter. The switch is
a Nch MOSFET transistor. This is low Ron.
