TLV62130A: 5Vout recommendations and HS RdsON @ 5Vin

Part Number: TLV62130A
Other Parts Discussed in Thread: TPS62130A

Dear team,

Could you please help me with the following two questions ?

Thanks a lot !!

  1. TLV62130A datasheet recommend a 5Vout max, I suppose this includes the resistors tolerance, which means a 5.1Vout (for example), would absolutely not harm the device and is included in the recommended range ?
  2. TLV62130A will be used to generate a 5Vout @ 3A (max), from a 8 to 12V typical. In some situation, the product will be powered from a 5V supply, and TLV62130A will be in 100% DC mode. Could we provide a RdsON indication for the HS FET when Vin is 5V  (4.8Vmin) ? (datasheet stops at 6Vin)

Wishing you a nice day,

Best regards,

PA

    You should not program the output voltage higher than 5V. If, through tolerances or otherwise, Vout ends up higher than 5V, it is ok--as long as the abs max ratings (for the VOS pin, for example) are kept.

    The TPS62130A offers up to 6Vout. As well, its D/S has a spec for Rdson at 3Vin. You can use this same number for TLV62130A and interpolate to get an approximate value at 5Vin.

    Hello Chris,
    Thank you!
    Vout will be programmed to 5.0V, but the tolerance might get the final output voltage higher than that.

    Best regards,
