The DIO6650 is a synchronous step-up DC/DC

converter. That is based on constant Off

Time/PSM controller topology. The IC enters PSM

mode automatically at light load, the goal is to

improve efficiency and reduce quiescent current.

The DIO6650 provides a complete power supply

solution for products powered by one or two

Alkaline, Ni-Cd, or Ni-MH battery cells. The

implemented boost converter is based on a

constant Off Time/PSM controller topology using

an internal synchronous rectifier to obtain

MH or 5V at 120mA from Two Cells

Up to 94% Efficiency
