Positive Doubling Charge Pumps with Shutdown  
in a SOT-23 Package  
Features  
General Description  
• Charge Pumps in 6-Pin SOT-23A Package  
• >99% Typical Voltage Conversion Efficiency  
• Voltage Doubling  
The TC1240/TC1240A is a doubling CMOS charge  
pump voltage converter in a small 6-Pin SOT-23A  
package. The TC1240 doubles an input voltage that  
can range from +2.5V to +4.0V, while the TC1240A  
doubles an input voltage that can range from +2.5V to  
+5.5V. Conversion efficiency is typically >99%. Internal  
oscillator frequency is 160 kHz for both devices. The  
TC1240 and TC1240A have an active-high shutdown  
that limits the current consumption of the devices to  
less than 1 µA.  
External component requirement is only two capacitors  
for standard voltage doubler applications. All other  
circuitry (including control, oscillator and power  
MOSFETs) are integrated on-chip. Typical supply cur-  
rent is 180 µA for the TC1240 and 550 µA for the  
TC1240A. Both devices are available in a 6-Pin SOT-  
23A surface mount package.  
• Input Voltage Range, TC1240: +2.5V to +4.0V,  
TC1240A: +2.5V to +5.5V  
• Low Output Resistance, TC1240: 17(Typical)  
TC1240A: 12(Typical)  
• Only Two External Capacitors Required  
• Low Supply Current, TC1240: 180 µA (Typical)  
TC1240A: 550 µA (Typical)  
• Power-Saving Shutdown Mode (1 µA Maximum)  
• Shutdown Input Fully Compatible with 1.8V Logic
