Switched-Capacitor Voltage Doublers ABSOLUTE MAXIMUM RATINGS
IN to GND ...+6V to -0.3V Operating Temperature Range OUT to GND ...+12V, VIN - 0.3V MAX1682EUK/MAX1683EUK ...-40°C to +85°C OUT Output Current..50mA Junction Temperature ..+150°C Output Short-Circuit Duration ...1sec (Note 1) Storage Temperature Range ...-65°C to +160°C Continuous Power Dissipation (TA = +70°C) Lead Temperature (soldering, 10sec) ...+300°C SOT23-5 (derate 7.1mW/°C above +70°C)...571mW Soldering Temperature (reflow) ...+260°C
Note 1:
Avoid shorting OUT to GND, as it may damage the device. For temperatures above +85°C, shorting OUT to GND even instantaneously will damage the device. 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.
ELECTRICAL CHARACTERISTICS
(VIN = +5.0V, capacitor values from Table 2, TA = 0°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.)

Note 2:
Once started, the MAX1682/MAX1683 typically operate down to 1V.
