Product Details
The MAX680 is a +5V to ±10V voltage converter.
A positive step-up charge pump is used to develop +10V fomr 5V and an
inverting charge pump is used to generate the -10V output.
The MAX680 only requires four external capacitors for operation.
The device has a high efficiency of typically 95% for voltage conversion.
Features
- 95% Voltage-Conversion Efficiency
