Synchronous DC-DC Step down Regulator comprising of Controller IC and Power MOSFET

DESCRIPTION
NN30310AA is a synchronous DC-DC Step down Regulator (1-ch) comprising of a Controller IC and two power MOSFETs and employs the hysteretic control system.
By this system, when load current changes suddenly, it responds at high speed and minimizes the changes of output voltage.
Since it is possible to use capacitors with small capacitance and it is unnecessary to add external parts for system phase compensation, this IC realizes downsizing of set and reducing in the number of external parts. Output voltage is adjustable by user.
Maximum current is 3 A.
