ABSOLUTE MAXIMUM RATINGS (1)
Supply Voltage VIN .......................–0.3V to +28V
Switch Voltage VSW ................. –1V to VIN + 0.3V
Bootstrap Voltage VBS....VSW – 0.3V to VSW + 6V
FB, COMP and SS Pins.................–0.3V to +6V
Thermal Resistance (4)
SOIC8E ..................................50...... 10... °C/W
PDIP8 ....................................104..... 45... °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.
