产品概述
XC9280A75CYR-G is a XC9280 series 18V bootstrap synchronous step-down DC/DC converter with built-in Nch-Nch driver transistors, it is 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 1.8 to 7.0V using external resistors (RFB1, RFB2). 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. 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. Application includes digital TV, set top box, security camera, smart meter, security system.
