LT8336 in shutdown mode

We are trying to use the EN input of LT8336 to turn off output voltage, but we still see 12.2V out with 12.6V input voltage and EN/UVLO 0V. Is this expected behavior or is there something wrong with our design/board?

  • Hello Nir,

    to avoid this additional work I would recommend to use a DC/DC regulator in a SEPIC topology, this requires a 2nd (or coupled inductor), but features a 'no DC path' between input and output. Hence you have a full shutdown without any additional load switch.

    LT8330, LT8362 or LT8365 feature your voltage and current range, low IQ and AEC-Q100 qual.

    kind regards
