SY7069 - 1MHz Synchronous Boost

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 PMO.

SY7069 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
