ZXSC300  
SINGLE OR MULTI CELL LED DRIVER SOLUTION  
DESCRIPTION  
the switching transistor.  
The ZXSC300 is a single or m ulti cell LED driver  
designed for applications where step-up voltage  
conversion from very low input voltages is required.  
These applications m ainly operate from single 1.5V or  
1.2V battery cells. The circuit generates constant  
current pulses that are ideal for driving single or  
m ultiple LED’s ove r a wide ra nge of ope ra ting  
voltages.  
The circuit can start up under full load and operates  
down to an input voltage of 0.8 volts. The solution  
configuration ensures optim um efficiency over a wide  
range of load currents, several circuit configurations  
a re p o s s ib le d e p e n d in g o n b a tte ry life ve rs u s  
brightness considerations.  
The ZXSC300 is offered in the SOT23-5 package  
which, when com bined with a SOT23 switching  
transistor, generates a high efficiency sm all size  
circuit solution. The IC and discrete com bination  
offers the ultim ate cost vs perform ance solution for  
single cell LED driving applications.  
The ZXSC300 is a PFM controller IC that drives an  
external Zetex switching transistor with a very low  
saturation resistance. These transistors are the best  
switching devices available for this type of switching  
conversion enabling high efficiency conversion with  
input voltages below 1 volt. The drive output of the  
ZXSC controller generates a dynam ic drive signal for
