IQ65033QMA10 ELECTRICAL CHARACTERISTICS (Continued)

Specifications subject to change without notice. Specifications in bold are guaranteed by design over the temperature range -40º to 125ºC.

Note 1: If the 5.0 V load current exceeds 100 mA, up to 200 mV of additional voltage drop is possible on the 5.0 V output.

Note 2: Maximum DC load at startup is 50 mA. Full load can be applied 700 ms after enable or 400 ms after the management power is up and running.

Note 3: Hold-up operation with Vin < 43 V not required by ATCA specification.

Note 4: 48 V output does not recover after hold-up event unless input is above Arm Hold-up threshold.

Note 5: Does not inhibit 48 V output and is non-latching.
