XC9281/XC9282 Series ETR05063-006 HiSAT-COT ® Control Extremely Small 600mA Step-Down DC/DC Converters ■GENERAL DESCRIPTION ☆Green Operation Compatible 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. ■(*) HAiSPATP-CLOITC: TAORTEIXONSのなオン■タイFムEATのURES ● Smart phones / Mobile phones Input Voltage Range ● Wireless earphone / Headset Output Voltage Range ● Wearable devices ● DSC / Camcorder ● Portable game consoles ● Smartcard ● Power supply for module Output Current Quiescent Current Oscillation Frequency Efficiency (fOSC=4MHz) Control Methods ● Various small power sources ■PCB IMAGE Protection Functions Functions Input / Output Capacitor Operating Ambient Temperature Package Environmentally : 2.5V ~ 5.5V : 0.7V ~ 1.15V (±2.0%) 1.2V ~ 3.6V (±1.5%) : 600mA : 11μA (XC9282 PWM/PFM Auto) : 4MHz, 6MHz : 90.0% (VIN=3.7V,VOUT=1.8V,IOUT=200mA) : HiSAT-COT Control PWM Control (XC9281) PWM/PFM Auto (XC9282) : Current Limit : Soft-Start, UVLO CL Discharge (Type B) : Ceramic Capacitor : - 40℃ ~ 105℃ : LGA-6B01 (1.2 x 1.2 x 0.3mm) WLP-5-06 (0.88 x 0.96 x 0.33mm) : EU RoHS Compliant, Pb Free ■TYPICAL APPLICATION CIRCUIT ■TYPICAL PERFORMANCE CHARACTERISTICS XC9281B18D / XC9282B18D (VOUT=1.8V) L = 1.0μH (DFE18SAN1R0MG0L) CIN = 4.7μF (GRM035R60J475ME15) CL = 4.7μF (GRM035R60J475ME15) VIN 2.5 ~ 5.5V CIN : 4.7uF (0.6x0.3x0.5mm) XC9281/XC9282 L : 1.0uH (1.0x0.5x0.55mm) VIN LX VOUT 1.8V / 600mA CE CE VOUT GND CL : 4.7uF (0.6x0.3x0.5mm) 1/31 XC9281/XC9282 Series ■BLOCK DIAGRAM 1) XC9281/XC9282 Series Type A CFB R1 Phase Compensation Current Limit VIN Error Amp.
