LTC1871-7  
High Input Voltage,  
Current Mode Boost,  
Flyback and SEPIC Controller  
DESCRIPTION  
FEATURES  
The LTC®1871-7 is a current mode, boost, flyback and  
SEPICcontrolleroptimizedfordriving6V-ratedMOSFETs  
inhighvoltageapplications.TheLTC1871-7worksequally  
well in low or high power applications and requires few  
componentstoprovideacompletepowersupplysolution.  
Theswitchingfrequencycanbesetwithanexternalresistor  
over a 50kHz to 1MHz range, and can be synchronized to  
an external clock using the MODE/SYNC pin. Burst Mode  
operation at light loads, a low minimum operating supply  
voltage of 6V and a low shutdown quiescent current of  
10μAmaketheLTC1871-7wellsuitedforbattery-operated  
systems. For applications requiring constant frequency  
operation, Burst Mode operation can be defeated using  
the MODE/SYNC pin. The LTC1871-7 is available in the  
10-lead MSOP package.
