TLV62569: Voltage from Vout to Vin

Dice-K

Part Number: TLV62569

Hi support team,

If a wrap-around voltage (0.5V to 5V) from an external circuit is input to the Vout side without energizing the Vin side, will the voltage on the Vin side become greater than 0V?

Hello Dice-K,

yes, the Vin side will become greater than 0V.

Best regards,

Andreas.

Hi Andreas,
Thank you for your reply.

Is Vin still affected by Vout even when EN is Low or High?

Hello Dice-K,

yes it is, because the body diode is the path from Vout to Vin, which is independent from EN.

Best regards,

Andreas.
