Overview
LN2115 Step-up DC/DC Converter —Backlight Driver ■ General Description The LN2115 Series is a fixed frequency, constant current step-up DC/DC converter ideal for driving LEDs used in backlighting applications on cellular phones, PDAs and digital cameras etc.
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  For White LED Drivers  Mobil phones, PHS  PDAs  Digital still cameras ■ Package  SOT-23-6L ■ Features  Input voltage range 2.
