SY20489C
Description
Features
The SY20489C is a high efficiency synchronous, step-up Boost converter designed for one-cell Li-Ion or Li-polymer, or a two to three-cell alkaline Ni-Cd or Ni-MH battery powered applications. It can convert down to 2.5V input voltage and up to 5.6V output voltage. It adopts NMOS for the main switch and PMOS for the synchronous switch.
The SY20489C can disconnect the output from input during the shutdown mode. When input voltage exceeds the regulated output voltage, the SY20489C enters bypass mode automatically.
