NOTES:
1. Connecting any input terminal to voltages greater than V
+
or less than GND may cause destructive latch-up. It is recommended that no
inputs from sources operating from external supplies be applied prior to "power up" of the TC660.
2. Derate linearly above 50
°
C by 5.5 mW/
°
C.
3. To prevent damaging the device, do not short V
OUT
to V
+
.
4. To maximize output voltage and efficiency performance, use low ESR capacitors for C
1
and C
2
.

*Static-sensitive device. Unused devices must be stored in conductive
material. Protect devices from static discharge and static fields. Stresses
above those listed under "Absolute Maximum Ratings" may cause perma-
nent damage to the device. These are stress ratings only and functional
operation of the device at these or any other conditions above those
indicated in the operation sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended periods may
affect device reliability.
