FEATURES  
DESCRIPTIO  
The LTC®3418 is a high efficiency, monolithic synchro-  
nous step-down DC/DC converter utilizing a constant  
frequency, current mode architecture. It operates from an  
input voltage range of 2.25V to 5.5V and provides a  
regulated output voltage from 0.8V to 5V while delivering  
up to 8A of output current. The internal synchronous  
power switch increases efficiency and eliminates the need  
for an external Schottky diode. Switching frequency is set  
by an external resistor or can be synchronized to an  
external clock. OPTI-LOOP® compensation allows the  
transient response to be optimized over a wide range of  
loads and output capacitors.

The LTC3418 can be configured for either Burst Mode  
operationorforcedcontinuousoperation.Forcedcontinu-  
ous operation reduces noise and RF interference while  
Burst Mode operation provides high efficiency by reduc-  
ing gate charge losses at light loads. In Burst Mode  
operation, external control of the burst clamp level allows  
the output voltage ripple to be adjusted according to the  
requirements of the application. A tracking input in the  
LTC3418 allows for proper sequencing with respect to  
another power supply.
