AMPLIFIER AND CURRENT
CONTROLLER

DESCRIPTION
The UTC UM609A is a monolithic IC that includes one
independent op-amp and another op-amp for witch the non
inverting input is wired to a 2.5V fixed voltage reference. This
device is offering space and cost saving in many applications like
power supply management or switching battery chargers.
