XD9267/XD9268 Series
36V Operation 600mA Synchronous Step-Down DC/DC Converters ETR05075-001 ☆AEC-Q100 Grade2 ■GENERAL DESCRIPTION
The XC9268 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 resistors (RFB1 and RFB2).
The soft-start time is internally set to 2.0ms (TYP.), but can be adjusted to set a longer time using an external resistor and capacitor.
With the built-in UVLO function, the driver transistor is forced OFF when input voltage becomes 2.7V or lower.
The output state can be monitored using the power good function.
Over-current protection and thermal shutdown are built in as protection function, and it can be used safely even in the case of short
circuit. Internal protection circuits include over current protection and thermal shutdown circuits to enable safe use. ■FEATURES ■APPLICATIONS
