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.
Key Features
2.5V minimum input voltage.
Adjustable output voltage from 2.5V to 5.5V.
Min 3A valley current limit.
Capable for seamless transition between boost and
bypass mode.
Load disconnect during shutdown.
Low RDS(ON) (main switch/synchronous switch) at
5.0V output: 50mΩ/90mΩ.

pass 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.
