  • Forum Post: Re: TPS63002 not working

    Chris Glaser
    When using the fixed versions of the IC on the EVM, you must replace R1 with a 0 Ohm resistor. You can remove R2 if you want. This connects the FB pin directly to Vout. Can you try testing with a lab power supply instead of the battery? Have you measured Vin on the board? If neither of the above...

    Because the TPS63000 family is so integrated and easy to use, there are very few thingst that could be wrong with the design. You need to confirm that each pin on the IC has the expected voltage. You also need to confirm that the GND and PGND pins are electrically connected on the PWB. Another thing...

  • Forum Post: Re: TPS63010 - Is the part capable of output current 2A

    Thomas Hoffmann
    Hi Poh Leong, what you are asking is related to physics. When you operate from a voltage below you desired output voltage, than the converter operates in boost mode. Basically the current drive capability is related to the switch current inside the chip. In a simplified way think of it like POUT can...

  • Forum Post: TPS63002 in parallel?

    Ahmet Serbes
    Hi all, We need Li-Ion to 5V to power up our application and we have determined to use two TPS63002 in parallel to get 5V/2A peak. We have set up a board, in which outputs of the TPS63002s are simply short-circuited. However, one of the TPS63002 starts to warm up (and more input current is drawn)...

  • Forum Post: TPS63002 Heating Up

    Aditya Ayachit
    (Please visit the site to view this file) Hi! Please find the attached PDF for the implemented TPS63002 design. The EN_USB signal is coming from the uc (An MSP430) When the IC is disabled, it is not heating up. But when enabled it heats up, even though no load is connected to it. ...

  • Forum Post: Re: TPS63002: What happens when incoming voltages go over the 5.5v maximum?

    Daniel Acevedo
    Though the device will regulate the output to 5V, operating outside of the recommended operating conditions may affect the reliability of the device. Have you considered the TPS63061? It has a wide VIN range and can supply 1.2A at 5V out over most VIN as visible in figure 2 of the datasheet and calculated...

    This is an answer that is already in the forum. A quick search will return the following post. https://e2e.ti.com/support/power_management/led_driverslcd_bias/int-led_driverslcd_bias/f/194/t/28403.aspx

  • Forum Post: Boost from Li-ion up to 7-10 V

    Gamin Inganela
    All, Is there a TI chip to convert from a single-cell Li-ion output voltage (in the range of 3.0 to 4.2 Volts) up to an output in the range of 7.0 to 10.0 Volts? Efficiency or current provision specs aren't too important. Until now, we have used the TPS63002 with good success for stepping up...
