TOREX XC9273 Sync Buck DC/DC Converter

Fast Transient Response Performance

The 5.5V, 3A XC9273 synch buck DC/DC converter incorporates Hi-SAT COT, TOREX’s own constant On-Time architecture, to deliver extremely fast transient response performance and high efficiency. With Hi-SAT the XC9273 only needs one low cost 47μF ceramic capacitor at the output side.

However, adding an extra capacitor will allow the user to reduce output ripple further if required. With a 0.6V reference voltage source the output voltage can be set freely from 0.8V using external resistors. The integral soft start time can be adjusted with an external capacitor (CSS) and a Power Good feature is also included to help with system power-up sequencing.

The XC9273 recently received an award of excellence in the semiconductor device division of the “Semiconductor of the Year 2017” awards hosted by the Electronic Device Industry News in Japan.
