HiSAT-COT ® Control Extremely Small 600mA Step-Down DC/DC Converters
XC9281 / XC9282
The XC9282 series are 600 mA 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.
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.
