2PCS LM2662 Switched Capacitor Negative Voltage Converter Module +5V/-5V 200mA
Maximum current 200mA, enough to supply the op amp negative supply, negative reference and other needs
The charge pump circuit is simple, small size, low ripple 15mv
Do not reverse the polarity of the input and output, as this may damage the module
Input voltage should not exceed the limit. LM2662 model maximum 5.5V, otherwise burn out
The charge pump output resistance is non-regulated, as the output current increases, the voltage will gradually decline, this is a normal phenomenon, be sure to know
