Chip Features Constant voltage and constant current control Precise internal voltage reference Few external components Easy to compensate Low supply current: 0.6mA Operating temperature range: -40℃～105℃
Chip Description
The EG4313 is a constant voltage and constant current control chip, specifically designed for high-precision constant current and constant voltage SMPS power supplies and battery charger systems.
The EG4313 integrates a 1.21V reference voltage source, two operational amplifiers, and a current sampling circuit. The 1.21V reference voltage source and operational amplifier form a precise voltage control circuit. Users can adjust the output voltage by setting the values of two external resistors. Simultaneously, the current sampling circuit and another operational amplifier form a precise current control circuit. Users can adjust the maximum current limit by setting the value of an external resistor, ensuring the entire system operates under constant voltage/constant current to prevent damage from excessive current or voltage.
