SY20492D
Description
The SY20492D is a high efficient, synchronous, stepup Boost converter designed for one-cell Li-Ion or Lipolymer, or a two to three-cell alkaline Ni-Cd or Ni MH battery powered applications. It can convert down to 0.85V input voltage. It adopts NMOS for the main switch and PMOS for the synchronous switch.
The SY20492D can disconnect the output from input during the shutdown mode. When input voltage exceeds the regulated output voltage, the SY20492D enters bypass mode automatically.
