TPL5111EVM: Query

Genius 5355 points
Part Number: TPL5111EVM
Other Parts Discussed in Thread: TPS61029, TPL5111

Hi Support,

Tested the DC/DC boost EVK.

Changed R2 to 1.5M ohm for VOUT to 4.3V.

The VOUT without load and it is working : 4.3V

After added the Load 100mA, the VOUT drop a bit to 4.12V.

Added 200mA loading, the VOUT become failed and no output voltage.

Because the datasheet TPS61029  don’t have the Vin VS I out chart reading.

I also do not know what happened, could you advise?

 


Thanks.

    Hello Ikon,

    Please post a new question that starts with TPS61029 instead of TPL5111. Our team only supports TPL5111, but it seems that this question is all about the boost converter. Another team will answer TPS61029 related questions.

    Regards,
    Hao
