ABSOLUTE MAXIMUM RATINGS (1)
Supply Voltage VIN ........................-0.3V to +20V
Switch Node Voltage VSW ............................ 21V
Boost Voltage VBS ..........VSW – 0.3V to VSW + 6V
All Other Pins..................................-0.3V to +6V
Junction Temperature...............................150°C
Thermal Resistance (4)
SOIC8.....................................90...... 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
Continuous Power Dissipation
(TA = +25°C)(2)
SOIC8……………………………………….1.38W
Lead Temperature ....................................260°C
Storage Temperature .............. -65°C to +150°C
Recommended Operating Conditions (3)
Input Voltage VIN ............................4.75V to 18V
Output Voltage VOUT.....................0.923V to 15V
Operating Junct. Temp (TJ)........-40°C to +125°C
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..
3) The device is not guaranteed to function outside of its
operating conditions.
4) Measured on JESD51-7, 4-layer board.
