Even faster response realized with ripple control
Rapid transient response DC-DC converter IC
MM3573XH
Announced on October 4, 2011
Overview
Due to diversification, there is an increasing need for electronic device power sources that operate at lower currents and higher currents. A voltage accurate of ± 1 to 5% is required, and, for ICs such as image processing ICs and memory which require a fast response, excellent transient characteristics are needed.
For voltage mode control and current mode control in conventional models, correction with external components was necessary and fine adjustment, such as phase control for every output condition, was indispensable.
Through use of ripple control, the <MM3573XH> realizes a faster transient response that conventional models and renders fine adjustment unnecessary.
