XC9289Series
ETR05090-001a
HiSAT-COT® Control, 1.5A Synchronous Step-Down DC/DC Converter
☆Green Operation compatibl
■GENERAL DESCRIPTION
The XC9289 series is 1.5A synchronous step-down DC/DC converters with a built-in P-channel driver FET and N-channel
driver FET.
The Output voltage is internally set in a range from 0.8V to 3.6V increments of 0.05V. Only an inductor and two capacitors
were connected externally.
Oscillation frequency is set to 1.2MHz or 3.0MHz can be selected for suiting to your particular application.
HiSAT-COT is a proprietary high-speed transient response technology for DC/DC converter which was minimized output
voltage during load fluctuations. It is Ideal for the applications with large instantaneous load fluctuations such as FPGAs and
equipment that requires stable output voltage.
The package is the ultra-small LGA-8B01 (1.2x1.4xh0.3 mm).
(*) 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.
