Part Number: PMP20183 Other Parts Discussed in Thread: LM3481 Hello,
I was looking for a design to supply 180 V at low current, and PMP20183 topology looked like a good candidate. How can I tweak this design to bring the voltage down a bit? I think…
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…
Charles,
It is difficult for me to be able to trouble shoot the circuit to find the issue. A few thoughts for you to consider:
- Are any components installed incorrectly, such as a diode installed backward. Very carefully check all components on the…

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
Part Number: LM3481 Other Parts Discussed in Thread: PMP20183 , Hi
Our customer refers PMP20183 to design the circuit for following requirement.
V_INPUT : DC 9V
V_OUTPUT : 260V (Max)
I_OUTPUT : 10mA(Max)
According to the requirement, PMP20183…

We designed prototype board based on PMP20183 referring the following thread.
However, we found strange output ramp up at start up. Please check the following image.

Part Number: LM3481 Other Parts Discussed in Thread: PMP , Hi,
I am considering the circuit of PMP 20183 using the LM 3481. I assume the following specifications. I calculated the peak current of the inductor (68 uH), but it flows about 1 A at the operating…
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.
Part Number: LM3488 Other Parts Discussed in Thread: PMP20183 Hello!
I am trying to make a boost converter using the Webench design (attached). The design parameters are 3-3.5V input, 48V at 0.01A output. I have built the circuit following the design…
Hello Mario,
We do not have an IC that supports this input and output voltage range directly. I think the best solution is to use a converter to generate a lower voltage and then increase the voltage with charge pumps, similar to PMP20183.
Please…
