    I forgot to explicitly link the reference design in question: https://www.ti.com/tool/TIDA-01232 https://www.ti.com/lit/gpn/tps7a47 Thanks!

  • RE: TPS7A52: Bias voltage

    Hello Andres, Thank you for your reply. I want to look at an alternative design by using two TPS7A52 in parallel. According to the specsheet this can be done by following the instructions in the "TI Designs: TIDA-01232 My concern is that this is…

  • TPS7A85: Serial vs Parallel Design for high reliability

    Part Number: TPS7A85 Other Parts Discussed in Thread: , TPS7A83A , TIDA-01232 Hi all, I need some advice. I have to use the TPS7A85 component to meet the following parameters: Input Voltage: 3.5V Output Voltage: 1V Output Current: 2A Allowable Ripple : 1mV …

  • RE: TINA/Spice/TPS7A85A: Current Sharing Parallel LDO using Ballast Resistor referencing TIDA-01232 or using control loop with sense resistors referencing TIDU-421?

    Resolved
    Thanks for response Ryan regarding the 15k resistors. Now how are the sense resistors calculated? along with the resistors at the input of the op amp? I know for the TIDA-01232, the document gives us the formula for calculating the ballast resistors…

  • RE: TPS7A54: Bias supply

    Resolved
    Hi Itoh-san, My fault i missed the current sharing part of the first question. Yes you can achieve this through current sharing. You will need to use ballast resistors or amplifiers though. There is a good app note below on how to use ballast resistors…

  • RE: TPS65185EVM: Design file of TPS65185EVM

    Resolved
    Hi Vinnie, Thanks for providing the additional details. Since the LDOs on this device do not have an accessible FB pin, the only way to potentially parallel two LDO1 outputs is to use ballast resistors. This reference design shows an example with a different…

  • RE: TPS7A88: Alternative solution for TPS7A8801 for the better thermal

    Resolved
    Hi Ella, I have a couple potential solutions for you: - You can connect multiple TPS7A8801 in parallel to lessen the current being pulled by the devices. The drawback to this solution is the complexity that it presents Here are some TI App notes…
