LTC3411A  
1.25A, 4MHz, Synchronous  
Step-Down DC/DC Converter  
FEATURES  
DESCRIPTION  
The LTC®3411A is a constant frequency, synchronous  
step-down DC/DC converter. Intended for medium power  
applications, it operates from a 2.5V to 5.5V input voltage  
range and has a user configurable operating frequency  
up to 4MHz, allowing the use of tiny, low cost capacitors  
and inductors 1mm or less in height. The output voltage is  
adjustablefrom0.8Vto5.5V. Internalsynchronouspower  
switches provide high efficiency. The LTC3411A’s current  
mode architecture and external compensation allow the  
transient response to be optimized over a wide range of  
loads and output capacitors.

Short-Circuit Protected  
Low Dropout Operation: 100% Duty Cycle  
Low Shutdown Current: I ≤ 1μA  
Q
The LTC3411A can be configured for automatic power  
saving Burst Mode operation (I = 40μA) to reduce gate  
charge losses when the load current drops below the level  
required for continuous operation. For reduced noise and  
RF interference, the SYNC/MODE pin can be configured to  
skip pulses or provide forced continuous operation.  
Output Voltages from 0.8V to 5V  
Q
Synchronizable to External Clock  
Supports Pre-Biased Outputs  
Small 10-Lead 3mm × 3mm DFN or MSOP Package  
APPLICATIONS  
To further maximize battery life, the P-channel MOSFET  
is turned on continuously in dropout (100% duty cycle).  
In shutdown, the device draws <1μA.
