Part Number: TPS55340

Hi team,

Please help recommend a 5V to +15V DCDC boost chip with EN and soft start function, which can adjust the rise time

Because the load capacitance is relatively large, it is hoped that a rise time of 50-100ms can be achieved.

if TPS55340 is suitable or do you have other recommend?

Thanks

Hi Lillian,

Thank you for using E2E forums, regarding your query for TPS55340 the SS capacitor is usually suggested to be around 0.047uF and with this you will get around 5 - 6ms of rise time or starting up time when the device starts up. May I know why do you want such a big startup time?
