Panasonic is pleased to announce the NEW NN30 Series synchronous DC/DC Step Down Regulator (1-ch). The NN30 Series integrates power MOSFETs that employ a hysteretic control system. This provides a high-speed response that minimizes output voltage fluctuations in the presence of load current spikes.

Simplification of the applied circuit is facilitated by the use of small capacitance capacitors as well as lack of need for external system phase compensation. This leads to the downsizing of the overall design and the requirement of a smaller number of separately sourced parts. The NN30 Series has a user adjustable output voltage and a maximum current of 10A.
