The XC9274 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 XC9274 only needs one low cost 47μF ceramic capacitor at the output side, whilst competitors often need multiple capacitors to achieve similar levels of performance. However adding an extra capacitor will allow the user to reduce output ripple further if required.
Hi-SAT COT also provides less fluctuation in oscillation frequency against load and input voltage when compared to traditional COT control architectures.
With a 0.6V reference voltage source the output voltage can be set freely from 0.8V using external resistors. Furthermore, it is possible to control the output voltage dynamically using an external digital-to-analog converter (DAC).
