NN30 Series Synchronous DC/DC Step-Down Regulator

Fast response featuring Panasonic’s original hysteretic DC/DC core

The NN30 Series from Panasonic integrates power MOSFETs that employ a hysteretic control system. This provides a high-speed response to minimize 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 10 A. Panasonic's NN30 Series Synchronous DC/DC Step-Down Regulator
