TC1240  
Positive Doubling Charge Pump with Shutdown  
in SOT Package  
GENERAL DESCRIPTION  
FEATURES  
The TC1240 is a doubling CMOS charge-pump voltage  
converter in a small 6-Pin SOT-23A package. TC1240  
doubles an input voltage which can range from +2.5V to  
+4.0V. Conversion efficiency is typically >99%. Internal  
oscillator frequency is 160kHz for the TC1240. The TC1240  
has an active high shutdown which limits the current con-  
sumption of the device to less than 1µA.  
External component requirement is only two capacitors  
for standard voltage doubler applications. All other circuitry,  
includingcontrol, oscillator, powerMOSFETsareintegrated  
on-chip. Typical supply current is 180µA and the device is  
available in a 6-Pin SOT-23A surface mount package.
