1.0A Step-Down Synchronous DC/DC Converters with HiSAT-COT

News

Torex Semiconductor has developed a new series of 1.0A output, step-down, synchronous DC/DC converters equipped with Torex’s unique HiSATCOT fast transient response control.

The XC9257/XC9258 series are step-down synchronous DC/DC converters with an output current of 1.0A and Torex’s unique HiSAT-COT fast transient response control.

Compared to regular COT control, Torex’s HiSAT-COT control enables greater suppression of frequency fluctuations caused by the load and input voltage, resulting in response speed eight times faster than previous products, and output voltage drop of 50%.

PWM control (XC9257) or PWM/PFM auto switching control (XC9258) can be selected for the operation mode, and a fast response, low ripple and high efficiency are obtained over the entire load range, from light loads to heavy loads.

The output voltage can be set internally to a value from 0.8V to 3.6V (±2.0%) in steps of 0.05V.
