LTC3417A-2  
Dual Synchronous  
1.5A/1A 4MHz  
Step-Down DC/DC Regulator  
FEATURES  
DESCRIPTION  
The LTC®3417A-2 is a dual constant frequency, synchro-  
nous step-down DC/DC converter. Intended for medium  
power applications, it operates from a 2.25V to 5.5V input  
voltagerangeandhasaconstantprogrammableswitching  
frequency, allowing the use of tiny, low cost capacitors  
and inductors 2mm or less in height. Each output voltage  
is adjustable from 0.8V to 5V. Internal synchronous, low

A user selectable mode input allows the user to trade  
off ripple voltage for light load efficiency. Burst Mode  
operation provides high efficiency at light loads, while  
Pulse Skip mode provides low ripple noise at light loads.  
A phase mode pin allows the second channel to operate  
in-phase or 180° out-of-phase with respect to channel 1.  
Out-of-phase operation produces lower RMS current on

Phase Pin Selects 2nd Channel Phase Relationship

To further maximize battery life, the P-channel MOSFETs  
are turned on continuously in dropout (100% duty cycle)  
and both channels draw a total quiescent current of only  
100μA. In shutdown, the device draws <1μA.
