HiSAT-COT ® Control 700mA Inductor Built-in Step-Down “micro DC/DC” Converters

The XCL244 series is a synchronous step-down micro DC/DC converter which integrates an inductor and a control IC in one tiny package (2.25mmx1.5mm, h=0.75mm). An internal coil simplifies the circuit and enables minimization of noise and other operational trouble due to the circuit wiring.
The Output voltage is internally set in a range from 0.8V to 3.6V increments of 0.05V.
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.

(*) 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.
