  • PMP20183: Lowering PMP20183 voltage

    Resolved
    Part Number: PMP20183 Hello, I am unfamiliar with PMP20183 topology, but need a high voltage source running at low current, and this design seems to fit my needs. However, I would like to run it 10% lower than 200V (because of the max voltage of my photodiode…

  • LM3481: Changing parameter of PMP20183

    Resolved
    Part Number: LM3481 Other Parts Discussed in Thread: PMP20183 Hi I want to confirm reason why PMP20183 will operate in DCM. Is it correct that PMP20183 should operate in DCM because of IL < ΔILpp? BestRegards

  • RE: LM3481: Changing parameter of PMP20183

    Hi, Yes, you are right: the output power is the output voltage x the output current. However, in this ref design, the Po should be the boost stage output power, which also includes the power losses of the charge pump. As a quick estimate, use 50% as…

  • RE: LM3478: 12V to 200V boost converter

    Resolved
    Hi Haroon, Thank you for your response. I suggested the PMP20183 9V-15V Input Voltage Boost Converter (200V@10mA) Reference Design which seems to meet his requirements. It has a voltage trippler to boost the voltage to 200V. Is it suitable for his application…

  • PMP20183: how to make the output HV is tunnable?&How to Inverting the Boost HV to -200V?

    TI Thinks Resolved
    Part Number: PMP20183 1. How to make the output HV is tunnable with the control of MCU(PWM for wxample)? The HV range is 50-200V, is tunable. 2 How to Inverting the Boost HV to -200V? I need a negtive HV output. Thanks.

  • RE: LM5156-Q1: WEBENCH Power Designer vs LM5155/56 DC/DC Boost Controller Design Tool which one should be used?

    Resolved
    Hi David, thank you for using the E2E forum. Boosting from 12V up to 200V is quite a big conversion ratio. This only can work with DCM when using a Boost design. We have an reference design which would fit very well to your requirement - this uses a small…
