DIO6155

High-Efficiency, 2 A Output Synchronous Step-Down

Converter

Features

Descriptions



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

The DIO6155 is a high-efficiency, high-frequency

synchronous step-down DC-DC regulator IC

capable of delivering more than 2 A output

currents.

2.5 V to 5.5 V input voltage range

Adjustable output voltage:

0.6 V to 5 V



More than 2 A output current capability

Low quiescent current: 10 μA

2 MHz switching frequency minimizes the

external components

The DIO6155 features a selection function that

switches the device between the force pulse

width modulation (FPWM) and auto mode. When

the SEL pin is driven HIGH, the DIO6155 enters

(FPWM) mode. The device enters the auto mode if

the SEL pin is LOW.



Operation mode: FPWM or auto mode

High efficiency at light load

100% duty cycle for the lowest dropout

Output discharge function

Protection:

If the DIO6155 is selected to work under FPWM

mode, the device works with ultra-low output

ripple. Under auto mode, the DIO6155 works in

PWM (Pulse Width Modulation) mode under

medium to heavy load. In such conditions, the

•

Short-circuit protection

Thermal shutdown protection

Over-current protection



Package: 1.5 mm x 1.5 mm DFN-6

DIO6155 functions with a 2 MHz switching

frequency to minimize the size of the inductor and

output capacitor. If the load drops to meet the

light load condition, the DIO6155 automatically

enters PSM (Power Save Mode) for high

efficiency.

Applications



IP network cameras

Portable electronics

Solid state drive

The DIO6155 has a fast transient response feature.

The device operates over a wide input range from

2.5 V to 5.5 V with very low R_DS(ON)to minimize the

conduction loss. The DIO6155 is capable of

delivering output down to 0.6 V with a feedback

voltage of ±6 mV accuracy over -20°C to 85°C

junction temperature.
