Switched-Capacitor Voltage Doublers
ABSOLUTE MAXIMUM RATINGS
IN to GND .................................................................+6V to -0.3V
OUT to GND .......................................................+12V, VIN - 0.3V
OUT Output Current............................................................50mA
Output Short-Circuit Duration .................................1sec (Note 1)
Continuous Power Dissipation (TA = +70°C)
SOT23-5 (derate 7.1mW/°C above +70°C)...................571mW
Operating Temperature Range
MAX1682EUK/MAX1683EUK ...........................-40°C to +85°C
Junction Temperature ......................................................+150°C
Storage Temperature Range .............................-65°C to +160°C
Lead Temperature (soldering, 10sec) .............................+300°C
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 âAbsolute Maximum Ratingsâ 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.
