  • TPS62230: TPS62230 Startup Time for Cyclone 10 LP FPGA Application

    TI Thinks Resolved
    Part Number: TPS62230 Other Parts Discussed in Thread: TPS62808 Tool/software: Hi, I am currently considering using the TPS62230 as a 2.5 V supply for an Altera Cyclone 10 LP FPGA (VCCIO = 2.5 V). According to the FPGA requirements, the supply voltage…

  • TPS62230: DESIGN REVIEW

    TI Thinks Resolved
    Part Number: TPS62230 Tool/software: Dear Sir, We have used your TPS62237DRYT buck converter in your design to generate 3V from a 5V input source. Please review my design and let us know if any changes are required in it. FYI, the load at 3V3 is drawing…

  • TPS62230: Reverse current during shutdown

    Resolved
    Part Number: TPS62230 Hi support team, There appears to be current backflow from the SW pin to the VIN pin during shutdown. The moment the VIN voltage drops and becomes the same voltage as VOUT, a reverse current of just under 100mA occurs. Since…

  • TPS62230: Voltage on EN pin when there is no voltage on VIN

    Resolved
    Part Number: TPS62230 Is it okay to briefly have 3.0V on the EN pin of the TPS62237 after voltage is removed from VIN? VIN will be removed when a cable is unplugged and it will take me about 3 mS to detect that and drive the EN pin low. I do see in…
