BQ25601: withstand voltage of 0.047 uF between BTST and SW

BQ25601: Capacitance for between BTST nad SW

Part Number: BQ25601

Hi Angelo,

Is there a restriction to the capacity of the BTST to SW capacitors?
And, what is the minimum capacitance (uF) required for this capacitor?

Best regards,
Chiaki

    Chiaki,

    The design is to use 0.047uF capacitance and all the performance evaluation is under the condition. For your 7.5Vin application, we recommended 0.047uF 25V capacitor considering the margin and cap derating with DC voltage and the capacitor maximum voltage is about 14V (Vin + VREGN).
