2 MHz, Synchronous Boost  
DC-to-DC Converter  
Data Sheet  
ADP1607  
FEATURES  
GENERAL DESCRIPTION  
Up to 96% efficiency  
The ADP1607 is a high efficiency, synchronous, fixed  
frequency, step-up dc-to-dc switching converter with an  
adjustable output voltage between 1.8 V and 3.3 V for use  
in portable applications.  
0.8 V to VOUT input voltage range  
Low 0.9 V input start-up voltage  
1.8 V to 3.3 V output voltage range  
23 µA quiescent current  
Fixed PWM and light load PFM mode options  
Synchronous rectification  
True shutdown output Isolation  
Internal soft start, compensation, and current limit  
2 mm × 2 mm, 6-lead LFCSP  
The 2 MHz operating frequency enables the use of small  
footprint, low profile external components. Additionally, the  
synchronous rectification, internal compensation, internal fixed  
current limit, and current mode architecture allow for excellent  
transient response and a minimal external part count.  
Other key features include fixed PWM and light load PFM  
mode options, true output isolation, thermal shutdown (TSD),  
and logic controlled enable. Available in a lead-free, thin, 6-lead  
LFCSP package, the ADP1607 is ideal for providing efficient  
power conversion in portable devices.  
Compact solution size  
APPLICATIONS  
1-cell and 2-cell alkaline and NiMH/NiCd powered devices  
Portable audio players, instruments, and medical devices  
Solar cell applications  
Miniature hard disk power supplies  
Power LED status indicators
