SY20492 Overview
The SY20492 is a high-efficiency, synchronous Boost converter designed for single-cell lithium (Li-ion or Li-polymer) or two-cell to three-cell nickel (alkaline Ni-Cd or Ni-MH) battery-powered applications. It can operate down to 1.8V input voltage. It uses NMOS for the main switch and PMOS for the synchronous switch.
