LED DRIVER BOOST CONVERTER  
DESCRIPTION  
The ZXSC400 is a voltage m ode boost converter in the SOT23-6 package. Its low  
feedback voltage allows the current in a chain of LEDs to be set and accurately  
m onitored with a single resistor giving m inim al losses. Its excellent load and line  
regulation m eans that for the full supply range from lithium -ion cells, the LED  
current will typically change by less than 1%. Using high efficiency Zetex switching  
transistors with ratings of 20V and higher allow m any LEDs to be chained in series  
for the best LED current m atching possible.

DESIGN INFORMATION  
IC operation description  
Block diagram  
Bandgap Reference  
All threshold voltages and internal currents are  
derived from a tem perature com pensated bandgap  
reference circuit with a reference voltage of 1.22V  
nom inal.  
Dynam ic Drive Output  
Depending on the input signal, the output is either  
“LOW” or “HIGH”. In the high state a 2.5m A current  
source (m ax drive voltage = VCC-0.4V) drives the base  
or gate of the external transistor. In order to operate  
th e e xte rn a l s w itch in g tra n s is to r a t o p tim u m  
efficiency, both output states are initiated with a short  
transient current in order to quickly discharge the base  
or the gate of the switching transistor.  
2µs  
Sw itching Circuit  
The switching circuit consists of two com parators,  
Com p1 and Com p2, a gate U1, a m onostable and the  
drive output. Norm ally the DRIVE output is “HIGH”; the  
external switching transistor is turned on. Current  
ram ps up in the inductor, the switching transistor and  
external current sensing resistor. This voltage is  
sensed by com parator, Com p2, at input ISENSE. Once  
the current sense voltage across the sensing resistor  
exceeds 30m V, com parator Com p2 through gate U1  
triggers a re-triggerable m onostable and turns off the  
output drive stage for 2␮s. The inductor discharges to  
the load of the application. After 2␮s a new charge  
cycle begins, thus ram ping the output voltage. When  
the output voltage reaches the nom inal value and FB  
gets an input voltage of m ore than 300m V, the  
m onostable is forced “on” from Com p1 through gate  
U1, until the feedback voltage falls below 300m V. The  
above action continues to m aintain regulation.

APPLICATIONS INFORMATION  
Sw itching transistor selection  
Capacitor Selection  
The choice of switching transistor has a m ajor im pact A sm all value, low ESR ceram ic capacitor is required to  
on the converter efficiency. For optim um perform ance, filter the output, typically 1␮F to 4.7␮F.  
a bipolar transistor with low VCE(SAT) and high gain is  
required. The VCEO of the switching transistor is also an  
im portant param eter as this sees the full output  
voltage when the transistor is switched off. Zetex  
SuperSOT™ transistors are an ideal choice for this  
application.  
Generally an input capacitor is not required, but a sm all  
ceram ic capacitor m ay be added to aid EMC, typically  
1␮F to 4.7␮F.  
Inductor Selection  
Th e in d u cto r va lu e m u s t b e ch o s e n to s a tis fy  
perform ance, cost and size requirem ents of the overall  
solution.  
Schottky diode selection  
As with the switching transistor, the Schottky rectifier  
diode has a m ajor im pact on the converter efficiency. A  
Schottky diode with a low forward voltage and fast  
recovery tim e should be used for this application.  
Inductor selection has a significant im pact on the  
co n ve rte r p e rfo rm a n ce . Fo r a p p lica tio n s w h e re  
efficiency is critical, an inductor with a series resistance  
of 250m ⍀ or less should be used.  
The diode should be selected so that the m axim um  
forward current rating is greater or equal to the  
m axim um peak current in the inductor, and the  
m axim um reverse voltage is greater or equal to the  
output voltage. The Zetex ZHCS Series m eet these  
needs.

The ZXSC400 offers a shutdown m ode that consum es  
a standby current of less than 5␮A. When the voltage at  
the STDN pin between 1V and 8V (and also open circuit),  
the ZXSC400 is enabled and the driver is in norm al  
operation. When the voltage at the STDN pin is 0.7V or  
lower, the ZXSC400 is disabled and the driver is in  
shutdown m ode. The SHDN input is a high im pedance  
current source of 1␮A typ. The driving device can be an
