Dual Operational and Voltage The NCP4300A is a monolithic integrated circuit specifically designed to control the output current and voltage levels of switchmode 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.
