GENERAL DESCRIPTION  
The ADP1606/ADP1607 are high efficiency, synchronous, fixed  
frequency, step-up dc-to-dc switching converters with a 1.8 V  
fixed output voltage option and a 1.8 V to 3.3 V adjustable  
output voltage option for use in portable applications.  
current limit, and current mode architecture allow 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 ADP1606/ADP1607 are ideal for providing  
efficient power conversion in portable devices.  
The 2 MHz operating frequency enables the use of small  
footprint, low profile external components. Additionally, the  
synchronous rectification, internal compensation, internal fixed
