Part Number:TPS61021A
Hello,
My customer is using TPS61021A to drive LED. They met some issue during evaluation.
When they decease the input voltage, the input current will suddenly increase at certain input voltage level(in the video below, the input voltage to IC is around 2V) and back to normal after decreasing the input voltage further more.
(Please visit the site to view this video)
below is the schematic, output voltage is 3.28V, output current in above test is set to around 330mA.
Best regards,
Victor
