SY7069B Datasheet | Silergy

5.5V Maximum Output, 3A Valley Current, 1MHz Synchronous Boost with Auto Bypass Function General Description SY7069B 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. SY7069B can disconnect the output from input during the shutdown mode. When input voltage exceeds the regulated output voltage, SY7069B enters bypass mode automatically.
