TPS54332: response time that inductor current intersects current limit thresold to switch off internal high side FET

Part Number: TPS54332

Hi Team,

The datasheet shows current limit threshold is 6.5A (typical).
Do you have response time that inductor current intersects current limit thresold to switch off internal high side FET?

Best Regards,
Yaita

  • Yaita-san,

    The TPS54332 current limit is cycle by cycle current limit.  The current is monitored in real time during the high side FET on time and is detected instantly with only some gate delays.  The only exception is if current limit is reached during the blanking time (minimum controllable on time).  In that case, the current limit is actuated at the end of the blanking time.
