• Manufacturer Part Number: ltc3459es6-trpbf
• Description: 10v Micropower Synchronous Boost Converter In Thinsot
• Manufacturer: Linear Technology Corporation

TYPICAL APPLICATIONS
Very low operating quiescent current and synchronous
operation allow for greater than 85% conversion effi ciency
in many applications. Lower output voltages will result in
lower effi ciencies since the N- and P-channel R
