Tiny step-down DC-DC converters with HiSAT-COT fast transient response control

Torex Semiconductor has developed two new series of step-down, synchronous DC-DC converters with the company's 'unique' HiSAT-COT fast transient response control in an ultra-small package (1.2mm × 1.4mm × 0.3mm). Compared to regular COT control, the HiSAT-COT control enables greater suppression of frequency fluctuations caused by the load and input voltage. The response speed is eight times faster than previous products, and the output voltage drop is reduced by 50%, says the company.
