5. Pinning information
5.1 Pinning
5.2 Pin description
(1) This is not a supply pin. The substrate is attached to this
pad using conductive die attach material. There is no
electrical or mechanical requirement to solder this pad.
However, if it is soldered, the solder land should remain
floating or be connected to GND.

6. Functional description
[1] H = HIGH voltage level; L = LOW voltage level; X = don’t care; Z = high-impedance OFF-state.
7. Limiting values
[1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
[2] For SO24 packages: above 70 C the value of P
tot
derates linearly with 8 mW/K.
For (T)SSOP24 packages: above 60 C the value of P
tot
derates linearly with 5.5 mW/K.
For DHVQFN24 packages: above 60 C the value of P
tot
derates linearly with 4.5 mW/K.
