General Description
The G5115/G5117/G5119 are high efficiency boost
converters with constant current output that drives up to
4 white LEDs. The continuous LED current is set with
the FB pin regulated voltage across an external sense
resistor (Rs) connected from that pin to ground. A dim-
ming PWM waveform to SHDN pin controls LED av-
erage current proportional to its duty makes the bright-
ness of LEDs also proportional to the duty.
Low FB regulation voltage and low switch turned on
resistance result in high converting efficiency from wide
battery voltage range to high LED series voltage.
An over-voltage protection prevents device damage
while LEDs is open. It is easy to release protection
state by just put the load path closed.
