DESCRIPTION

· The NCP4300A is a monolithic integrated circuit designed for controlling output current and voltage in switchmode battery chargers and power supplies.
· It includes a precision 2.6 V shunt reference and two operational amplifiers.
· Op-Amp 1 is for voltage control with its non-inverting input connected to the reference internally.
· Op-Amp 2 is for current control with both inputs uncommitted.
· Available in an 8-lead surface mount package.
