LTC3412A  
3A, 4MHz, Monolithic  
Synchronous Step-Down Regulator  
U
DESCRIPTIO  
FEATURES  
The LTC®3412A 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 3A of output current. The internal synchronous  
power switch with 77mΩ on-resistance increases effi-  
ciency and eliminates the need for an external Schottky  
diode. Switchingfrequencyissetbyanexternalresistoror  
can be synchronized to an external clock. 100% duty cycle  
provides low dropout operation extending battery life in  
portable systems. OPTI-LOOP® compensation allows the  
transient response to be optimized over a wide range of  
loads and output capacitors.

The LTC3412A 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  
application requirements.
