Switched-Capacitor Voltage Inverters
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
Note 2: All -40°C to +85°C specifications are guaranteed by design.
Note 3: The MAX870/MAX871 may draw high supply current during startup, up to the minimum operating supply voltage. To guarantee
2
Note 1: Capacitor contribution is approximately 20% of the output impedance [ESR + 1 / (pump frequency x capacitance)].
