TLV62084A: VINの立ち上がり時間について

Part Number: TLV62084A

本デバイスをVINとENをショートして使用しようと思います。

正常に出力を得るためにVINの立上り時間に規定はありますか。

(何m Sで何Vの単調増加が必要とか何mS以内に何Vにする必要がある等)

TPS54425PWPのような低電圧保護(UVP)機能はあるでしょうか。

以上よろしくお願いします。」

I would like to use this device by shorting VIN and EN. Is there a regulation for the rise time of VIN to obtain a normal output? (How many mS and how many V should be monotonically increasing, how many V should be within how many mS, etc.) Does it have an under voltage protection (UVP) feature like the TPS54425PWP?

Hi Shinji,

I would like to reply to your question as Moheddin is out of office.

EN and VIN can be tied together. There is no limit on the slew rate of VIN. The device will start up after VIN is above the UVLO rising threshold.

The device has UVLO protection

Best regards,

Varun
