Description  
The RC4191/4192/4193 series of monolithic ICs are low  
power switch mode regulators intended for miniature power  
supply applications. These DC-to-DC converter ICs provide  
all of the active components needed to create supplies for  
micropower circuits. Contained internally are an oscillator,  
switch, reference, comparator, and logic, plus a discharged  
battery detection circuit.  
The standard application circuit requires just seven external  
components for step-up operation: an inductor, a steering  
diode, three resistors, a low value timing capacitor, and an  
electrolytic filter capacitor. The combination of simple  
application circuit, low supply current, and small package  
make the RC4193 adaptable to a wide range of miniature  
power supply applications.  
These regulators can achieve up to 85% efficiency in most  
applications while operating over a wide supply voltage  
range, 2.2V to 30V, at a very low quiescent current drain of  
215 mA.  
The RC4193 is most suited for single ended step-up  
(V  
OUT  
> V ) circuits because the NPN internal switch tran-  
IN  
sistor is referenced to ground. It is complemented by Fair-  
child Semiconductor's micropower switching regulator, the  
RC4391, which is dedicated to step-down (V  
OUT  
< V ) and  
IN  
inverting V  
OUT  
= -V ) applications. Between the two  
IN  
devices the ability to create all three basic switching regula-  
tor configurations is assured. Refer to the RC4391 data sheet  
for step-down and inverting applications.  
Block Diagram  
4191/92/93  
The RC4191/92/93 series of micropower switching regula-  
tors consists of three devices, each with slightly different  
specifications. The RM4191 has a 1.5% maximum output  
voltage tolerance, 0.2% maximum line regulation, and oper-  
ation to 30V. The RC4192 has a 3.0% maximum output  
voltage tolerance, 0.5% maximum line regulation, and oper-  
ation to 30V. The RC4193 has a 5.0% maximum output volt-  
age tolerance, 0.5% maximum line regulation, and operation  
to 24V. Other specifications are identical for the RC4191,  
RC4192 and RC4193. Each type is available in commercial,  
industrial, and military temperature ranges, and in plastic  
and ceramic DIPs and S0-8 packages.
