DIO6182X/DIO6182XA

High-Efficiency, 1 A/2 A/3 A/4 A Output Synchronous

Step-Down Converter with 1%

Features

Descriptions



Low R_DS(ON)for internal switches (25 mΩ)

The DIO6182X/DIO6182XA is a high-efficiency,

high-frequency synchronous step-down DC-DC

regulator IC capable of delivering up to 4 A output

currents.

2.5 V to 5.5 V input voltage range

Adjustable output voltage application:

0.6 V to 5 V



Low operating quiescent current: 10 μA

2 MHz typical switching frequency minimizes

the external components

The DIO6182X operates in auto mode, which

includes two modes, the PWM (Pulse Width

Modulation) mode and the PSW (Power Save Mode)

mode. The device operates in PWM mode for

medium to heavy loads. In such conditions, the

DIO6182X operates at a switching frequency of

2 MHz to minimize the size of the inductor and

output capacitor. When the load current drops to

light load conditions, the DIO6182X automatically

enters PSM mode for high efficiency. The

DIO6182XA operates in forced PWM, in which the

device maintains continuous on mode operation

and maintains extremely low output voltage ripple

in the whole load range.



Operation mode:

DIO6182X: Auto mode

DIO6182XA: Forced PWM operation

High-efficiency for light load

100% duty cycle for lowest dropout

Output discharge function

Power good output indicator

Protection:



•

Short circuit protection

Thermal shutdown protection

Overcurrent protection



Package: 1.5 mm x 1.5 mm DFN-6

The DIO6182X/DIO6182XA has a fast transient

response feature. The device operates over a

wide input ranging from 2.5 V to 5.5 V with very

low R_DS(ON)to minimize the conduction loss. The

DIO6182X/DIO6182XA can deliver an output down

to 0.6 V with a feedback voltage of ±6 mV

accuracy over -20°C to 85°C junction temperature.

Applications



IP network cameras

Portable electronics

Solid state drives

Industrial PCs

Multifunctional printers
