Low Duty Cycle, 600 mA, 3 MHz Synchronous  
Step-Down DC-to-DC Converter  
ADP2102  
FEATURES  
GENERAL DESCRIPTION  
Input voltage range: 2.7 V to 5.5 V  
600 mA maximum load current  
95% efficiency  
The ADP2102 is a synchronous step-down dc-to-dc converter  
that converts a 2.7 V to 5.5 V unregulated input voltage to a lower  
regulated output voltage with up to 95% efficiency and 1%  
accuracy. The low duty cycle capability of the ADP2102 is ideal for  
USB applications or 5 V systems that power up submicron subvolt  
processor cores. Its 3 MHz typical operating frequency and excel-  
lent transient response allow the use of small, low cost 1 μH  
inductors and 2.2 μF ceramic capacitors. At medium-to-high  
load currents, it uses a current mode, pseudofixed frequency pulse-  
width modulation to extend battery life. To ensure the longest  
battery life in portable applications, the ADP2102 has a power save  
mode (PSM) that reduces the switching frequency under light  
load conditions to significantly reduce quiescent current.  
Low duty cycle operation  
Only 3 tiny external ceramic components  
3 MHz typical operating frequency  
Fixed output voltage from 0.8 V to 1.875 V  
Adjustable output voltage up to 3.3 V  
0.01 μA shutdown supply current  
Automatic power save mode  
Internal synchronous rectifier  
Internal soft start  
Internal compensation  
Enable/shutdown logic input  
Undervoltage lockout  
Current limit protection  
Thermal shutdown  
The ADP2102 is available in both fixed and adjustable output  
voltage options with 600 mA maximum output current. The preset  
output voltage options voltage are 1.875 V, 1.8 V, 1.5 V, 1.375 V,  
1.25 V, 1.2 V, 1.0 V, and 0.8 V. The adjustable voltage option is  
available from 0.8 V to 3.3 V. The ADP2102 requires only three  
external components and consumes 0.01 μA in shutdown mode.  
Small 8-lead, 3 mm × 3 mm LFCSP package  
APPLICATIONS  
USB powered devices  
WLAN and gateways  
Point of loads  
The ADP2102 is available in an 8-lead LFCSP package and is  
specified for the −40 °C to +85 °C temperature range.  
Processor core power from 5 V  
Digital cameras  
PDAs and palmtop computers  
Portable media players, GPS
