Dual 550mA, 1MHz Synchronous Boost Regulator with Output Disconnect & Soft-Start in a 3mm x 3mm DFN
Burst Mode® operation lowers quiescent current to only 18uA (both channels), providing extended battery run time in handheld applications. The LTC3535 is an ideal part for handheld dual boost applications in which small solution size and maximum battery run time are defining factors.
LTC3535EDD is available from stock in 12-lead 3mm x 3mm DFN package. 1,000-piece pricing starts at $2.95 each. For more information, visit www.linear.com.
