SY20492 - High-Efficiency 2A Valley-Current Synchronous Boost Converter
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
