DESCRIPTION

  

  The SL1571Bis a high-power density, asynchronous boost 

converter with a 120mΩ power switch to provide a high 

efficiency and small size solution in portable systems. The 

SL1571B has input voltage range from 2.6 V to 5.5 V to 

support applications with different power supply. The device

has 3A switch current capability and can provide an output 

voltage up to 16V.

  The SL1571B also implements a soft-start function and an 

adjustable switching peak current limit function.

In addition, the device provides 20V output overvoltage 

protection, and thermal shutdown protection.
