FEATURES  
DESCRIPTIO  
Accurate Input/Output Current Control: ±5% Over  
The LT®1618 step-up DC/DC converter combines a tradi-  
tionalvoltagefeedbackloopandauniquecurrentfeedback  
loop to operate as a constant-current, constant-voltage  
source. Thisfixedfrequency, currentmodeswitcheroper-  
ates from a wide input voltage range of 1.6V to 18V, and
