This new project was started with the objective of establishing novel core technologies for power supply ICs
aligned with superior product development by leveraging ROHM’s vertically integrated production
system to thoroughly pursue not only circuit and layout design, but also process technologies.
ROHM was able to create three new power supply technologies through trial and error

ROHM Establishes QuiCur™, an Innovative Power Supply Technologythat Maximizes the Response Performance of Power Supply ICs
Nano Cap™ provides ultra-stable control of output by improving response in analog circuits while minimizing parasitic factors related to wiring andamplifiers. In this case, QuiCur™ high-speed load response technology is also utilized to reduce output capacitance to 100nF, less than 1/10th thatof conventional, while maintaining stable operation. QuiCur™ is named after ROHM’s original 'Quick Current' circuit that makes it possible tomaximize load response characteristics without causing instability in the feedback circuits of power supply ICs. By expanding the stable control
