ABSOLUTE MAXIMUM RATINGS (1)
Supply Voltage (VIN).....................–0.3V to +40V
Switch Voltage (VSW)............ –0.3V to VIN + 0.3V
BST to SW.....................................–0.3V to +6V
All Other Pins.................................–0.3V to +6V
Thermal Resistance (4)
3x3mm QFN10 .......................50...... 12... °C/W
SOIC8E ..................................50...... 10... °C/W
θJA
θJC
Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature TJ (MAX), the junction-to-
ambient thermal resistance θJA, and the ambient temperature
TA. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by PD (MAX) = (TJ
(MAX)-TA)/θJA. Exceeding the maximum allowable power
dissipation will cause excessive die temperature, and the
regulator will go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage.
