Compact, 600 mA, 3 MHz,  
Step-Down DC-to-DC Converter  
Data Sheet  
ADP2108  
FEATURES  
GENERAL DESCRIPTION  
Peak efficiency: 95%  
The ADP2108 is a high efficiency, low quiescent current step-  
down dc-to-dc converter manufactured in two different  
packages. The total solution requires only three tiny external  
components. It uses a proprietary, high speed current mode,  
constant frequency PWM control scheme for excellent stability  
and transient response. To ensure the longest battery life in  
portable applications, the ADP2108 has a power save mode that  
reduces the switching frequency under light load conditions.  
3 MHz fixed frequency operation  
Typical quiescent current: 18 μA  
Maximum load current: 600 mA  
Input voltage: 2.3 V to 5.5 V  
Uses tiny multilayer inductors and capacitors  
Current mode architecture for fast load and line  
transient response  
100% duty cycle low dropout mode  
Internal synchronous rectifier  
Internal compensation  
The ADP2108 runs on input voltages of 2.3 V to 5.5 V, which  
allows for single lithium or lithium polymer cell, multiple alkaline  
or NiMH cell, PCMCIA, USB, and other standard power sources.  
The maximum load current of 600 mA is achievable across the  
input voltage range.  
Internal soft start  
Current overload protection  
Thermal shutdown protection  
Shutdown supply current: 0.2 μA  
Available in  
5-ball WLCSP  
5-lead TSOT  
The ADP2108 is available in fixed output voltages of 3.3 V, 3.0 V,  
2.5 V, 2.3 V, 1.82 V, 1.8 V, 1. 5 V, 1.3 V, 1.2 V, 1.1 V, and 1.0 V. All  
versions include an internal power switch and synchronous rect-  
ifier for minimal external part count and high efficiency. The  
ADP2108 has an internal soft start and is internally compensated.  
During logic controlled shutdown, the input is disconnected  
from the output and the ADP2108 draws less than 1 μA from  
the input source.  
Supported by ADIsimPowerdesign tool  
APPLICATIONS  
PDAs and palmtop computers  
Wireless handsets  
Digital audio, portable media players  
Digital cameras, GPS navigation units  
Other key features include undervoltage lockout to prevent deep  
battery discharge and soft start to prevent input current over-  
shoot at startup. The ADP2108 is available in 5-ball WLCSP and  
5-lead TSOT packages. The ADP2109 provides the same features  
and operations as the ADP2108 and has the additional function  
of a discharge switch in the WLCSP package.
