Datasheet Summary
Application Note: SY7069
5.5V Maximum Output, 3A Valley Current, 1MHz Synchronous Boost with Auto Bypass Function
General Description
SY7069 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 NiMH 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.
SY7069 can disconnect the output from input during the shutdown mode. When input voltage exceeds the regulated output voltage, SY7069 enters bypass mode automatically.
