Part Number: LM25122-Q1

Dear all,

This device has VCC regulator current limit at 50mA.

When the current flow over this limit, does this device also enter Hiccup mode?

Best regards,

    When it hit the limit, the VCC will drop and the switching may be stopped because of VCC UV. If the current reduces, the VCC may recover and the IC can re-start. But it is different than the Hiccup mode referred to in the datasheet.
