FEATURES  
DESCRIPTION  
The LM3354 is a CMOS switched capacitor DC/DC  
converter that produces a regulated output voltage by  
automatically stepping up (boost) or stepping down  
(buck) the input voltage. It accepts an input voltage  
between 2.5V and 5.5V. The LM3354 is available  
with standard output voltages of 1.8V, 3.3V, 4.1V  
(ideal for white LED applications), and 5.0V. If other  
output voltage options between 1.8V and 5.0V are  
desired, please contact your TI representative.
