TC110  
PFM/PWM Step-Up DC/DC Controller  
Features  
General Description  
• Assured Start-up at 0.9V  
The TC110 is a step-up (Boost) switching controller  
that furnishes output currents of up to 300mA while  
delivering a typical efficiency of 84%. The TC110  
normally operates in pulse width modulation mode  
(PWM), but automatically switches to pulse frequency  
modulation (PFM) at low output loads for greater  
efficiency. Supply current draw for the 100kHz version  
is typically only 50µA, and is reduced to less than  
0.5µA when the SHDN input is brought low. Regulator  
operation is suspended during shutdown. The TC110  
accepts input voltages from 2.0V to 10.0V, with a  
guaranteed start-up voltage of 0.9V.

• Programmable Soft-Start  
• 84% Typical Efficiency  
• Small Package: 5-Pin SOT-23A  
Applications  
The TC110 is available in a small 5-Pin SOT-23A  
package, occupies minimum board space and uses  
small external components (the 300kHz version allows  
for less than 5mm surface-mount magnetics).  
• Palmtops  
• Battery-Operated Systems  
• Positive LCD Bias Generators  
• Portable Communicators
