ETR05063-001

HiSAT-COT ® Control Extremely Small 600mA Step-Down DC/DC Converters

☆GreenOperation 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, 0.47uH 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 (C_IN) and the output capacitance (C_L), realizing that the mounting area

including peripheral components can be reduced to 6.6 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 which Torex developed and the DC/DC converters with HiSAT-COT technology are ideal

for LSI's that require high precision and high stability power supply voltage.
