TPS65132: The cap. voltage rating at CFLY1/CFLY2

Part Number: TPS65132

Hi there,

     Is it possible to use  2.2uF cap. with 10Vdc rating on between CFLY1 and CFLY2 pin? This cap. is a charge pump cap. for negative output. Thanks.

    Hello Alan,

    As shown in the datasheet typical application circuits, using a 2.2uF capacitor is ok for low current (<40mA) applications but a 4.7uF capacitor is recommended for higher current applications (>40mA). Also, a 16V or higher rated capacitor is recommended because of possible overlap of switching states as well higher DC biased capacitor value.

    Kind Regards,
