    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

    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…

    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…

    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…
