Electrical Characteristics
Limits in standard typeface are for T
less otherwise specified: V+ = 5V, C
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
temperatures 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
ambient temperature, and θ
Note 4: In the test circuit, capacitors C
output voltage and efficiency.
Note 5: Min. and Max. limits are guaranteed by design, test, or statistical analysis.
Note 6: Typical numbers are not guaranteed but represent the most likely norm.
Note 7: The minimum input high for the shutdown pin equals 40% of V+.
Note 8: The maximum input low for the shutdown pin equals 20% of V+.
Note 9: Specified output resistance includes internal switch resistance and capacitor ESR. See the details in the application information for simple negative voltage
converter.
Note 10: The output switches operate at one half of the oscillator frequency, f
