  • TPS56C230: TPS56C230 Vin short with PGND

    Part Number: TPS56C230 Hi Customer TPS56C230 will be burned, and the specific performance is that Vin is short-circuited to PGND. I checked the customer's layout and found that AVDD and PGND are connected under the chip without using 0 ohm resistors. Does…

  • TPS56C230: Double pulse problem

    TI Thinks Resolved
    Part Number: TPS56C230 The TPS56C230 on the customer's board has a double pulse problem, the following is the schematic diagram and PCB diagram. The customer's remote feedback wiring is a long line with a via hole. I cut the PCB line and passed the…

  • RE: TPS56C230: double pulse problem

    Hi Qingze, It looks like the TPS56C230 VOUT plane is routed to the remote load VOUT (the green wide area?). Can you please confirm if that is the case? Ideally, they should just use sense lines on another layer to connect the VOUT from the TPS56C230 …

  • TPS56C230: After Boot, the output will continue to climb and cannot be stabilized

    Part Number: TPS56C230 Hi TI When I start it, the output will continue to climb after it reaches the set value. Can I check those parts please? The experiment I have done is as follows, it looks like there are have some issue on the TPS56C230 1. Connect…

  • TPS56C230: TPS56C230RJER blown up..

    Part Number: TPS56C230 Hi We have used TPS56C230RJER in our design to generate 3.3V power rail with following specs: - Vin : 6 V - 8.4 V ( 2 cell lithium ion battery) - Vout: 3.3V - Iout: 8A We used TI WebBench to design the power supply. The design report…

  • TPS56C230: Accuracy of MODE Pin Resistor

    Resolved
    Part Number: TPS56C230 Hi, Teams! I want to use TPS56C230 in FCCM. Page 13 of the datasheet says to use 1% resistors for RM_H and RM_L. Why do we need 1% accuracy? The Mode pin voltage is VCC* (within 15.5% ±1.4%) even with 5% precision resistors…

  • TPS56C230: MODE pin voltage > 20%*VCC

    Resolved
    Part Number: TPS56C230 Hi team, What will be expected when users set the MODE pin voltage over >20% * VCC. Since they want to use resistors with lower accuracy (5%) Regards, Hayashi
