IN SC70-6 DESCRIPTION The ZXLD1100 is a PFM inductive boost converter designed for driving 2, 3 or 4 series connected white LEDs from a Li-Ion cell and up to 8 LEDs from a 5V supply. The device operates from an input supply of between 2.5V and 5.5V and provides an adjustable output current of up to 50mA. The ZXLD1100 includes the output switch and peak current sense resistor, and can operate with a maximum output voltage of 28V. Quiescent current is typically 60␮A and a shutdown function is provided to reduce this current to less than 500nA in the 'off' state. Output current can be adjusted by applying a PWM control signal to the 'Enable' pin.
