XC9280 Series 18V Operation 3.0A Synchronous Step-Down DC/DC Converters ETR05064-003 ■GENERAL DESCRIPTION The XC9280 series is 18V bootstrap synchronous step-down DC/DC converter with built-in Nch-Nch driver transistors, the operating voltage range is 4.5V~18.0V, designed to allow the use of ceramic capacitors. 0.75V reference voltage source is incorporated in the IC, and the output voltage can be set to a value from 1.8V to 7.0V using external resistors (RFB1, RFB2). Switching frequency is 1.

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 th.

Step-Down DC/DC Converter

XC9280 Series 18V Operation 3.0A Synchronous Step-Down DC/DC Converters ETR05064-003 ■GENERAL DESCRIPTION The XC9280 series is 18V bootstrap synchronous step-down DC/DC converter with built-in Nch-Nch driver transistors, the operating voltage range is 4.5V~18.0V, designed to allow the use of ceramic capacitors. 0.75V reference voltage source is incorporated in the IC, and the output voltage can be set to a value from 1.8V to 7.0V using external resistors (RFB1, RFB2). Switching frequency is 1.2MHz. In PWM/PFM automatic switchover control, IC can change the control method between PWM and PFM based on the output current requirement and as a result IC can achieve high efficiency over the full load range. XC9280 has a fixed internal soft start time which is 0.95ms (TYP.), additionally the time can be extended by using an external resistor and capacitor. With the built-in UVLO function, the driver transistor is forced OFF when input voltage goes down to 3.33V (TYP.) or lower. Over current protection and thermal shutdown are embedded and they secure a safety operation. ■APPLICATIONS ● Digital TV ● Set Top Box ● Security camera ● Smart meter ● Security system ■FEATURES Input Voltage Range Output Voltage Range FB Voltage Oscillation Frequency Output Current Control Method Soft-start Time Protection function Output Capacitor Package Environmentally Friendly : 4.5V ~ 18V (Absolute Max 20V) : 1.8V ~ 7.0V or VIN x 0.7 : 0.75V±1.5% : 1.2MHz : 3A peak 2.0A DC (VIN=12V, VOUT=5V) : PWM.
