描述 Description
The SY20419is a high efficient, synchronous, step-up Boost converter designed for one-cellLi-Ion or Li-polymer, or a two to three-cell alkaline Ni-Cd or Ni-MH batterypowered applications. It can convert down to 1.8V input voltage. It adopts NMOSfor the main switch and PMOS for the synchronous switch.
The SY20419 can disconnect the output from input during theshutdown mode. When input voltage exceeds the regulated output voltage, the SY20419enters bypass mode automatically.
