Note 1:
Absolute maximum ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when operating the device
beyond its rated operating conditions.
Note 2:
OUT may be shorted to GND for one second without damage. However, shorting OUT to V+ may damage the device and should be avoided. Also, for tem-
peratures above 85˚C, OUT must not be shorted to GND or V+, or device may be damaged.
Note 3:
The maximum allowable power dissipation is calculated by using P
DMax
= (T
JMax
− T
A
)/θ
JA
, where T
JMax
is the maximum junction temperature, T
A
is the
ambient temperature, and
θ
JA
is the junction-to-ambient thermal resistance of the specified package.
Note 4:
In the test circuit, capacitors C
1
and C
2
are 47 µF, 0.2Ω maximum ESR capacitors. Capacitors with higher ESR will increase output resistance, reduce output
voltage and efficiency.
Note 5:
In doubling mode, when V
out
>
5V, minimum input high for shutdown equals V
out
− 3V.
Note 6:
Specified output resistance includes internal switch resistance and capacitor ESR.
Note 7:
For LM2663, the oscillator frequency is 150 kHz.
Note 8:
The output switches operate at one half of the oscillator frequency, f
OSC
= 2f
