  • TPS61097A-33: Low Voltage Output with Load

    Part Number: TPS61097A-33 Hi Team, I would like to seek your insight into this matter. I used 20uF input cap and 4.7uF output and also tried 10uH inductor, it still does not provide 3.3v at the output. Here I would like to clarify that on No load…

  • TPS61097A-33: Improved DC/DC drop at low battery voltage

    Part Number: TPS61097A-33 Hi Team, After 2.4V voltage input to the VBAT, the LED 8EA (5 seconds) operation produces a lot of voltage drop and enters CUT OFF. Is there any way to minimize the voltage drop on the DC/DC side? 1. Check voltage drop…

  • RE: TPS61221: Vout not equal to Vin when EN pin is pulled to ground. Also, Vout ~2.8V instead of 3.3v even when EN is pulled high and load ~100mA

    Resolved
    Hi Anupam: Sorry to notice that: d. TPS61097A-33 the current limit is too small. e. TPS61291 the minimum VIN is 0.9V. As I mentioned, TPS61201 is a good choice.
