Electrical Characteristics
Limits in standard typeface are for T

= V
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under which operation of
the device is guaranteed. Operating Ratings do not imply guaranteed performance limits. For guaranteed performance limits and associated test conditions, see the
Electrical Characteristics tables.
Note 2: All voltages are with respect to the potential at the GND pins (GND1-4, GND_BOOST, GND_WLED, GND_RGB).
Note 3: Battery/Charger voltage should be above 6V no more than 10% of the operational lifetime.
Note 4: Voltage tolerance of LP3933 above 6.0V relies on fact that V
(ON) at all conditions, National Semiconductor does not guarantee any parameters or reliability for this device.
Note 5: The total load current of the boost converter should be limited to 300 mA.
Note 6: Internal thermal shutdown circuitry protects the device from permanent damage. Thermal shutdown engages at T
140˚C (typ.).
Note 7: For detailed soldering specifications and information, please refer to National Semiconductor Application Note 1125: Laminate CSP/FBGA.
Note 8: The Human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin. The machine model is a 200 pF capacitor discharged
directly into each pin. MIL-STD-883 3015.7
