Other Parts Discussed in Thread: TPS40305,
The TPS40345 has a recommended operating condition down to -20C. The TPS40305 has recommended operating conditions down to -40C. The max ratings for both junctions are -40C.
Will the TPS40345 be fine starting from cold without any abnormal behavior, the operating curves are only defined starting from -20C?
The operating curves and block diagram for the TPS40345 are almost identical to the TPS40305.
