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.
