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.
