H3REG™: Key Technology for Fast Transient Response

H3Reg­™ is ROHM’s proprietary fast transient response control. The block diagram shown here illustrates the H3Reg control loop. H3Reg is a control method positioned as an advanced version of fixed on-time control in which a voltage comparator rapidly compares a reference voltage with a feedback voltage and rapidly switches an output switch. This is fast response that is independent of the switching frequency.
