DESCRIPTION
NN30332A 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 10 A.
APPLICATIONS
High Current Distributed Power Systems such as
・PCs
・HDDs
(Hard Disk Drives)
・SSDs
(Solid State Drives)
・Game
consoles
・Servers
・Security
Cameras
・Network
TVs
・Home
Appliances
・OA
Equipment etc.
