TPS92520-Q1: How much current needed for TPS92520-Q1 V5A pin under normal work/ switching mode

Part Number: TPS92520-Q1

Could you please kindly help to confirm how much current needed for TPS92520-Q1 V5A under normal work? Since we can only found V5A current under condition of stb and sleep mode, customer need to know the maximum current needed by V5A+V5D pin to determine which part of the power supply device they should choice to use. Thank you very much for your support to confirm.

Best regards

Jie

    Hello Jie,

    Since the gate drive current comes from V5D I would used the standby current for V5A added to V5D gate drive switching current (for your operating condition), using the maximum numbers in the electrical characteristics table and then add a little margin.  So that would be 5 mA and 20 mA (for 1 MHz both channels).

    Best Regards,
