TPS65219: Minimum capacitor value : effective value or not

Motoyasu Hattori

Part Number: TPS65219
Other Parts Discussed in Thread: LP8733,

Hi,

According to the LP8733 datasheet, we can find the "The minimum effective input capacitance to ensure good performance" sentense. How about TPS65219?

On the datasheet, Minimum of LDO Cout Min is 1.6uF. Also, LDO Output capacitor "C1005X7S1A225K050BC" is used on TI's EVM. If LDO outputs 2V, this capacitor is 1.4uF due to DC Bias. So we want to confirm whether minimum capacitor on the TPS65219 datasheet is used as effective value. Please advise us.

Thanks and best regards,
M.HATTORI.

Hi Hattori,

Thank You for your patience! The minimum local capacitance for the LDOs on the TPS65219 PMIC is 1.6uF (after derating).

Thanks,

Brenda
