frequency, current mode architecture. It operates from an  
input voltage range of 2.25V to 5.5V and provides a  
regulatedoutputvoltageequalto(0.5)VREF whilesourcing  
or sinking up to 3A of output current. An internal voltage  
divider reduces component count and eliminates the need  
for external resistors by dividing the reference voltage in  
half. The internal synchronous power switch with 85mΩ

for an external Schottky diode. Switching frequencies up  
to 2MHz are set by an external resistor.

Forced-continuous operation in the LTC3413 reduces  
noise and RF interference. Fault protection is provided by  
an overcurrent comparator that limits output current dur-  
ing both sourcing and sinking operations. Adjustable  
compensation allows the transient response to be opti-  
mized over a wide range of loads and output capacitors.
