XD9267/XD9268 Series ETR05075-004 36V Operation 600mA Synchronous Step-Down DC/DC Converters ☆AEC-Q100 Grade2 ■GENERAL DESCRIPTION The XD9267/XD9268 series are 36V operation synchronous step-down DC/DC converter ICs with a built-in P-channel MOS driver transistor and N-channel MOS switching transistor. The XD9267/XD9268 series has an operating voltage range of 3 V to 36 V, a switching frequency of 2.2 MHz, and the circuit scheme of synchronous rectification to be a highly efficient and stable power supply. An internal reference voltage source of 0.75 V is available, and the output voltage can be set to 1 V to 25 V by external res istors (RFB1 and RFB2). The soft-start time is internally set to 2.0ms (TYP.
