SY20489
Description
SY20489 is a high efficiency, synchronous, step-up 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 2.5V input voltage and up to 5.5V output voltage. It adopts NMOS for the main switch and PMOS for the synchronous switch.
SY20489 can disconnect the output from input during the shutdown mode. When input voltage exceeds the regulated output voltage, SY20489 enters bypass mode automatically.
