LN2115 Datasheet | natlinear

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 -...
