NCP4300A
Dual Operational Amplifier
and Voltage Reference
The NCP4300A is a monolithic integrated circuit specifically
designed to control the output current and voltage levels of switch
mode battery chargers and power supplies. This device contains a
precision 2.6 V shunt reference and two operational amplifiers.
Op–Amp 1 is designed to perform voltage control and has its
non–inverting input internally connected to the reference. Op–Amp 2
is designed for current control and has both inputs uncommitted. The
NCP4300A offers the power converter designer a control solution that
features increased precision with a corresponding reduction in system
complexity and cost. This device is available in an 8–lead surface
mount package.
