FEATURES  
DESCRIPTIO  
The LTC®3402 is a high efficiency, fixed frequency, step-  
up DC/DC converter that operates from an input voltage  
below1V.Thedeviceincludesa0.16ΩN-channelMOSFET  
switch and a 0.18Ω P-channel synchronous rectifier.  
Switching frequencies up to 3MHz are programmed with  
an external timing resistor and the oscillator can be  
synchronized to an external clock. An external Schottky  
diode is optional but will slightly improve efficiency.  
Synchronous Rectification: Up to 97% Efficiency  
2A Switch Current Rating  
Fixed Frequency Operation Up to 3MHz  
Wide Input Range: 0.5V to 5V  
Very Low Quiescent Current: 38μA (Burst Mode®  
Operation)  
2.6V to 5.5V Adjustable Output Voltage  
0.85V (Typ) Start-Up Voltage  
No External Schottky Diode Required (VOUT < 4.3V)  
Synchronizable Switching Frequency  
Burst Mode Enable Control  
Antiringing Control Reduces Switching Noise  
Quiescent current is only 38μA in Burst Mode operation,  
maximizing battery life in portable applications. Burst  
Mode operation is user controlled and can be enabled by  
driving the MODE/SYNC pin high. If the MODE/SYNC pin  
has either a clock or is driven low, then fixed frequency  
switching is enabled.  
PGOOD Output  
OPTI-LOOP® Compensation  
Very Low Shutdown Current: <1μA  
Small 10-Pin MSUOP Package  
Other features include a 1μA shutdown, antiringing con-  
trol, open-drain power good output, thermal shutdown  
and current limit. The LTC3402 is available in the 10-lead  
thermally enhanced MSOP package. Lower current appli-  
cations should use the 1A rated LTC3401 synchronous  
boost converter. Applications that require VOUT < 2.6V  
should use the LTC3424.
