GENERAL DESCRIPTION
Output voltage of up to 28V can be derived, and from a 3.2V input four white Led’s cab be driven in series or alternatively, using a 3.0V input, a network of six LEDs may be driven. Luminance of the LED’s is controlled by changing the duty cycle of a PWM signal applied to the CE pin.● LX limit Current 1000mA
●
APPLICATIONS
