Hi team,

Could you tell me the behavior when the following pins are OPEN or SHORT?

1: 17pin(ILIM)
2: 18pin(COMP)
3: 19pin(VCC)

Sincerely.
Kengo.

    Hi Kengo,

    1. ILIM pin Open: Works normally at no load and light load condition. No output at middle to heavy load conditions.

    ILIM Short to GND:  The inductor current may beyond the capability of the device. The IC can damage.

    2. COMP pin Open: The output voltage cannot be regulated well.

    COMP pin Short to GND: The output voltage cannot be regulated well. Vo less than target value.

    3. VCC pin Open: May result in silicon damage.

    VCC pin Short: The device doesn't work. No output voltage.
