TPS61046: R2=10Kohms is OK?

Part Number: TPS61046


Tool/software:

Hello,

My customer has a question about the low-side resistor R2 (between FB and GND). The datasheet says R2 should be kept smaller than 80 kΩ. How could it be small? Even 10KΩ is OK?

Best regards,

K.Hirano

    Hi Kazuhiko-san,

    There is no special limit by reducing the low-side feedback resistor value below 80kohm. 10kohm is ok for the feedback low-side resistor, the drawback is the larger leakage current through the feedback resistors which causes larger power consumption.

    BRs,
