XC9140 Series  
ETR04015-003  
Step-UpSynchronous PFM DC/DC Converter  
☆GreenOperation Compatible  
■GENERAL DESCRIPTION  
The XC9140 series are step-up synchronous DC/DC converters that support ceramic capacitors and have an internal 0.6Ω  
(TYP.) Nch driver transistor and an internal 0.65Ω (TYP.) Pch synchronous rectifier switch transistor. PFM control enables a low  
quiescent current, making these products ideal for portable devices that require high efficiency.  
When the output voltage is 3.3V and the load current is 1mA (XC9140Axx1 type and XC9140Cxx1 type), startup from an input  
voltage of VIN = 0.9V is possible which means that these products can be used in applications that start using a single alkaline or  
nickel-metal hydride battery. The output voltage can be set from 1.8V to 5.0V (±2.0%) in steps of 0.1V.  
The XC9140 features a load disconnect function to break continuity between the input and output at shutdown (XC9140A), and  
also a bypass mode function to maintain continuity between the input and output (XC9140C).  
A version with a UVLO (Under Voltage Lock-out) function is also available. This function enables the prevention of battery leakage  
by stopping IC’s operation when the input voltage is low. The standard product has a UVLO release voltage of 2.15V (±3.0%), and a  
custom version with a release voltage selectable from between 1.65V to 2.2V, in steps of 0.05V, is also available.
