CCL) Transient ...................................-0.3V to 14V
Linear Regulator Gate Drive, VLDGD ...................................................-0.3V to 9V
Current Sense Inputs (VSX, CSX) ....................................................... -0.3V to 12V
Error Amplifier Inputs (FBX, RF2, LDFB)........................................-0.3V to 5.5V
Input Voltage (SS/Enable, LDDIS) ...................................................-0.3V to5.5V
Output Drive Peak Current Source (HOx, LOx)....................................1A (500ns)
Output Drive Peak Current Sink (HOx, LOx) .......................................1A (500ns)
Operating Junction Temperature.................................................................. 150
°C
Storage Temperature Range...........................................................-65
°C to 150°C
RoHS Peak Package Solder Reflow Temperature
(40 second maximum exposure) ..................................................... 260°C (+0, -5)
Note:
Exceeding these ratings could cause damage to the device. All voltages are
with respect to Ground. Currents are positive into, negative out of specified
terminal.
The limitation on transient time is thermal and is due to zener diodes on the
supply pins, application of maximum voltages will increase current into that
pin and increase package power dissipation.
