Part Number: BQ25703A

Hi,

Please let me ask about the operating topology of DC/DC converter, such as voltage mode or current mode. the customer would like to know it to understand the load transient response.

Best Regards,

Satoshi / Japan Disty

    COMP2 is for the current loop. COMP1 is for the voltage loop.

    COMP1 and COMP2 parameters were carefully selected by design team to cover all corner cases;  and then, validation team spent a lot of time to do the evaluation with those COMP1 and COMP2 parameters.

    We don’t want customers spending a lot of time to repeat the same work. So, we recommend to keep same COMP1, COMP2 parameters and reasonable input/output capacitance.
