XC9281/XC9282Series  
ETR05063-003  
HiSAT-COT ® Control Extremely Small 600mA Step-Down DC/DC Converters  
☆Green Operation Compatible  
■GENERAL DESCRIPTION  
The XC9281/XC9282 series are 600mA synchronous rectification DC/DC converters adopting HiSAT-COT (*) control. Due to  
increasing the oscillation frequency to high frequency, coil with a size of 1.0 x 0.5 mm can be used. A 0.6 x 0.3 mm ceramic  
capacitor can be used for the input capacitance (CIN) and the output capacitance (CL), realizing that the mounting area including  
peripheral components can be reduced to 3.52 mm2.  
Due to increasing the oscillation frequency to a high frequency, the mounting area is reduced. Additionally, an efficiency equal  
to or higher than that of conventional products can realize by improving on-resistance and current consumption. Because of  
these features, XC9281/XC9282 series are ideal for equipment requiring miniaturization and low profile mounting area, and  
battery-powered equipment such as mobile equipment.  
Moreover, the high-speed transient response technology of the HiSAT-COT control makes it possible to minimize the  
fluctuation of the output voltage for a load transient condition. This feature is optimal for applications requiring a fast response  
and output voltage stability for an instantaneous load fluctuation like FPGA.  
(*)HiSAT-COT is a proprietary high-speed transient response technology for DC/DC converter which was developed by Torex. It is Ideal for the LSI's that require  
high precision and high stability power supply voltage.
