ZXLD1937  
ADJ USTABLE LED DRIVER WITH INTERNAL SWITCH IN TSOT23-5  
DESCRIPTION  
The ZXLD1937 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 o r a ' ch o p p e d ' o u tp u t cu rre n t. Th e PWM filte r  
between 2.5V and 5.5V and provides an adjustable com ponents are contained within the chip.  
output current of up to 50m A.  
The device is assem bled in the TSOT23-5 pin package  
with 1m m m axim um height profile.  
The ZXLD1937 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.  
a
Quiescent current is typically 60A and a shutdown  
function is provided to reduce this current to less than  
500nA in the 'off' state.
