10 A Synchronous DC-DC Step down Regulator

with low quiescent power mode

(V_IN= 4.5 V to 24 V, V_OUT= 0.75 V to 3.6 V)

FEATURES

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.

 High-Speed Response DC-DC Step Down Regulator

Circuit that employs Hysteretic Control System

 Hi-side 20 m (Typ), Low-side 6 m (Typ) MOSFETs

for High efficiency at 10 A

By this system, when load current changes suddenly,

it responds at high speed and minimizes the changes

of output voltage.

 Low Power Mode (discontinuous) for Light Load Efficiency

 Maximum Output Current : 10 A

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.

 Input Voltage Range : AV_IN= 4.5 V to 24 V,

PV_IN= 4.5 V to 24 V,

V₅= 4.5 V to 5.5 V

 Output Voltage Range : 0.75 V to 3.6 V

 Selectable Switching Frequency 430 kHz / 630 kHz

 Built-in Feed Back Resistors for 1.2 V / 1.05 V Output

Voltage (Also configurable using External Resistors)

 Adjustable Soft Start

Maximum current is 10 A.

APPLICATIONS

High Current Distributed Power Systems such as

・PCs

 Selectable Low Operating and Standby Quiescent

Current to achieve light load efficiency

・HDDs (Hard Disk Drives)

・SSDs (Solid State Drives)

・Game consoles

 Open Drain Power Good Indication for Output Over /

Under Voltage

 Built-in Under Voltage Lockout (UVLO),

Thermal Shut Down (TSD), Under Voltage Detection (UVD),

Over Voltage Detection (OVD), Short Circuit Protection (SCP)

Over Current Protection (OCP),

・Servers

・Security Cameras

・Network TVs

・Home Appliances

・OA Equipment etc.

 24 pin Plastic Quad Flat Non-leaded Package Heat

Slug Down (QFN Type)

(Size : 4 mm  4 mm  0.7 mm, 0.5 mm pitch)

Note : The application circuit is an example. The operation of

the mass production set is not guaranteed. Sufficient

evaluation and verification is required in the design of

the mass production set. The Customer is fully

responsible for the incorporation of the above

illustrated application circuit in the design of the

equipment.

Condition :

_IN= 12 V, V_OUTSetting = 1.05 V,

Switching Frequency = 430 kHz, Low Power Mode / Normal Mode,

L_O= 1 µH, C_O= 88 µF (22 µF x 4) #Including V5 current
