Last Time Buy Closest Alternative is AP5724WUG-7 ZXLD1101 ADJUSTABLE LED DRIVER WITH INTERNAL SWITCH IN TSOT23-5 DESCRIPTION The ZXLD1101 is a PFM inductive boost converter Output current can be adjusted by applying a PWM designed for driving 2, 3 or 4 series connected white control signal to the Enable pin. Depending upon the LEDs from a Li-Ion cell and up to 8 LEDs from a 5V control frequency, this will provide either a continuous supply. The device operates from an input supply of or a chopped output current. The PWM filter between 2.5V and 5.5V and provides an adjustable components are contained within the chip. output current of up to 50mA. The device is assembled in the TSOT23-5 pin package The ZXLD1101 includes the output switch and peak with 1mm maximum height profile. 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.
