  • TPS62125: Question regarding schematics and PCB

    TI Thinks Resolved
    Part Number: TPS62125 Hello community! I am working on a project where i should build buck converter(from 12-14.4v to 2.85V/300mA) that connected to LED which consumes 2.85v with 300mA. When i run DRC, I am having 4 of unconnected items issue mostly due…

  • TPS62125: About input current Tina simulation

    TI Thinks Resolved
    Part Number: TPS62125 Other Parts Discussed in Thread: TINA-TI Hello all, I simulated with TPS62125 to check the difference between input current with input cap and without input cap in the Tina-ti. The below pictures are the file that I download in…

  • TPS62125: Hysteresis resistor calculations

    TI Thinks Resolved
    Part Number: TPS62125 Hi, I'm trying to implement the TPS62125 Enable Threshold and Hysteresis settings (EN and EN_hys pins). The datasheet Application section is clear about how resistors R_EN1 and R_EN2 affect the enable thresholds. However, there's…

  • TPS62125: behavior

    TI Thinks Resolved
    Part Number: TPS62125 I'm using TPS62125 in a new project. Six boards were assembled until now. All of them are working, however some are showing an unexpected behavior. The schematic is showed below. Input voltage is 12.4V and output voltage is 4V…

  • MSP430FR2433: Power-on time when powered by TPS62125 Buck Converter

    TI Thinks Resolved
    Part Number: MSP430FR2433 Other Parts Discussed in Thread: TPS62125 , Hello, I am planning to power MSP430FR2433 with TPS62125. The total power-on time requirement is < 5ms. I calculate, from datasheet, that TPS62125 startup time is <400us. MSP430FR2433…
