NN30312A

VIN = 4.5 V to 30 V, 10 A

Synchronous DC-DC Step down Regulator

comprising of Controller IC and Power MOSFET

FEATURES

DESCRIPTION

NN30312A 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.

z High-Speed Response DC-DC Step Down Regulator

Circuit that employs Hysteretic Control System

z Two 11 mΩ (Typ.)

MOSFETs for High Efficiency at 10 A

z SKIP (discontinuous) Mode for Light Load Efficiency

z Up to 10 A Output Current

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.

z Input VoltageRange : AVIN : 4.5 V to 30 V,

PVIN : 4.5 V to 30 V,

Output Voltage Range : 0.75 V to 5.5 V

Selectable Switching Frequency 250 kHz , 750 kHz ,

1250 kHz

Maximum current is 10 A.

z Adjustable Soft Start

z Low Operating and Standby Quiescent Current

APPLICATIONS

z Open Drain Power Good Indication for Output Over ,

Under Voltage

High Current Distributed Power Systems such as

・HDDs (Hard Disk Drives)

・SSDs (Solid State Drives)

・PCs

z Built-in Under Voltage Lockout (UVLO),

Thermal Shut Down (TSD),

Over Voltage Detection (OVD),

Under Voltage Detection (UVD),

Over Current Protection (OCP),

Short Circuit Protection (SCP)

・Game consoles

・Servers

・Security Cameras

・Network TVs

z HQFN040-A3-0606B ( Size : 6 mm X 6 mm, 0.5 mm

pitch ), 40pin Plastic Quad Flat Non-leaded Package

Heat Slug Down (QFN Type)

・Home Appliances

・OA Equipment etc.
