ABSOLUTE MAXIMUM RATINGS
Input Voltage……................................................-0.3V to 30V
These are stress ratings only, and functional
operation of the device at these ratings or any other
above those indicated in the operation sections of the
specifications below is not implied. Exposure to
absolute maximum rating conditions for extended
periods of time may affect reliability.
Lx………………………………………..………….…-2V to 30V
FB……………....................................................-0.3V to 5.5V
Storage Temperature..……..…………...……-65 ° C to 150 ° C
Junction Temperature.....................................-40 ° C to 125 ° C
Lead Temperature (Soldering, 1…0 sec)….…………..300 ° C
ESD Rating……….…….…1kV LX, 2kV all other nodes, HBM
ELECTRICAL SPECIFICATIONS
Specifications are for T AMB =T J =25 ° C, and those denoted by ? apply over the full operating range, -40 ° C< T j <125 ° C. Unless
otherwise specified: V IN =4.5V to 29V, C IN = 4.7 μ F.
