ABSOLUTE MAXIMUM RATINGS (1) Thermal Resistance (5) θJA θJC
Supply Voltage V QFN16 (3mmx3mm) .. 70 .. 15 ... C/W IN .. 24V VSW ... -0.3V to 24.3V
Notes:
VSW (30ns) .. -3V to 28V 1) Exceeding these ratings may damage the device. V 2) Refer to “Configuring the EN Control”. SW (5ns) .. -6V to 28V 3) The maximum allowable power dissipation is a function of the VBST ... VSW + 5.5V maximum junction temperature TJ(MAX), the junction-to- VEN ... 12V ambient thermal resistance θJA, and the ambient temperature Enable Current I (2) TA. The maximum allowable continuous power dissipation at EN .. 2.5mA any ambient temperature is calculated by P All Other Pins .. –0.3V to +5.5V D(MAX)=(TJ(MAX)- TA)/θJA. Exceeding the maximum allowable power dissipation Continuous Power Dissipation (T will cause excessive die temperature, and the regulator will go A=+25)
