ADJ USTABLE LED DRIVER WITH INTERNAL SWITCH AND OPEN

CIRCUIT PROTECTION IN SC70-6

DESCRIPTION

Output current can be adjusted by applying a PWM

control signal to the 'Enable' pin. Depending upon the

control frequency, this will provide either a continuous

o r a ' ch o p p e d ' o u tp u t cu rre n t. Th e PWM filte r

com ponents are contained within the chip.

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 50m A.

The ZXLD1100 contains an internal avalanche diode to

protect the output switch. This allows the device to

operate indefinitely if the load is open circuit. Input

supply current during this condition is less than 1m A.

The ZXLD1100 includes the output switch and peak

cu rre n t s e n s e re s is to r, a n d ca n o p e ra te w ith

m axim um output voltage of 28V.

The device is assem bled in a low profile SC70-6 pin

package with industry standard pinout.

Quiescent current is typically 60␮A and a shutdown

function is provided to reduce this current to less than

500nA in the 'off' state.
