Compact, 800 mA, 3 MHz,  
Simple DVS, Buck Regulator  
ADP2147  
FEATURES  
GENERAL DESCRIPTION  
Input voltage: 2.3 V to 5.5 V  
Peak efficiency: 95%  
3 MHz fixed frequency operation  
Low quiescent current: 23 μA  
Ultralow shutdown current: 0.2 μA (typical)  
VSEL pin for simple dynamic voltage scaling (DVS)  
100% duty cycle low dropout mode  
Internal synchronous rectifier, compensation, and soft start  
Current overload and thermal shutdown protection  
Small, 6-ball, 1 mm × 1.5 mm WLCSP package  
The ADP2147 is a high efficiency, low quiescent current, step-  
down (buck) dc-to-dc regulator with an output voltage that can  
be switched between two different settings under the control of  
a select pin. The total solution requires only three tiny external  
components.  
The buck regulator automatically switches operating modes,  
depending on the load current level, to maximize efficiency. At  
high output loads, the buck regulator operates in PWM mode.  
When the load current falls below a predefined threshold, the  
regulator operates in power save mode (PSM), improving the  
light-load efficiency.  
APPLICATIONS  
The ADP2147 runs on input voltages of 2.3 V to 5.5 V, which  
allows for single lithium or lithium polymer cells, multiple  
alkaline or NiMH cells, PCMCIA, USB, and other standard  
power sources. The maximum load current of 800 mA is  
achievable across the input voltage range.  
PDAs and palmtop computers  
Wireless handsets  
Digital audio portable media players  
Digital cameras, GPS navigation units  
Low power portable medical equipment  
The ADP2147 is available with fixed output voltages from 0.8 V  
to 3.3 V. All versions include an internal power switch and  
synchronous rectifier for minimal external part count and high  
efficiency. The ADP2147 has an internal soft start and is  
internally compensated. During logic controlled shutdown, the  
input is disconnected from the output, and the ADP2147 draws  
less than 0.2 μA (typical) from the power source.  
Other key features include undervoltage lockout to prevent deep  
battery discharge and soft start to prevent input current over-  
shoot at startup. The ADP2147 is available in a 6-ball WLCSP.
