NCP5006
Output Load Drive
In order to optimize the built?in Boost capabilities, one
shall operate the NCP5006 in the continuous output current
mode. Such a mode is achieved by using and external
reservoir capacitor (see Table 1) across the LED.
At this point, the peak current flowing into the LED
diodes shall be within the maximum ratings specified for
these devices. Of course, pulsed operation can be achieved,
due to the EN signal Pin 4, to force high current into the
LED when necessary.
The Schottky diode D1, associated with capacitor C2
(see Figure 9), provides a rectification and filtering
function.
When a pulse?operating mode is acceptable:
? A PWM mode control can be used to adjust the output
current range by means of a resistor and a capacitor
connected across FB pin. On the other hand, the
Schottky diode can be removed and replaced by at
least one LED diode, keeping in mind such LED shall
sustain the large pulsed peak current during the
operation.
