Part Number: LMR38020 Hi,
I used LMR38020 for a DC-DC flybuck converter with 3 outputs, two of them being not isolated(3.3V/1.5A and 12V/200mA), one of them being isolated(12V/100mA). But the 3.3V output voltage ripple is very large at full load, how should…
Part Number: LMR38020 Other Parts Discussed in Thread: LM5160A Hi,
I would like to use LMR38020 for a DC-DC flybuck converter with 3 outputs, two of them being not isolated(3.3V/1.5A and 12V/200mA), one of them being isolated(12V/100mA). But I meet some…
Part Number: LMR38020 Other Parts Discussed in Thread: UCC21542 , , LM5165 I have designed an auxiliary power supply using the LMR38020 for conversion from 48V to 13V for an LLC resonant converter (160kHz switching frequency). The 13V output of the LMR38020…
Part Number: LMR38020 I built a flybuck auxiliary power supply using LMR38020FDDAR, which outputs two 12V. The designed non isolated 12V_ANA output power is 12W, and the isolated 12V_H output power is 3W. The voltage of the non isolated 12_ANA does not…
Part Number: LMR38020 Hi,
I'm expecting to have 15V on the output on the LMR38020 but I'm seeing the following output where the voltage is around 2V.
Any insight on what may be the issue? Thank you.

Part Number: LMR38020 Hello experts,
I'd like to confirm which JEDEC environment and JEDEC thermal board are used for each thermal metric in LMR38020. I drew the table below.
Could you check wthether my understanding is correct?
Thermal Metric …
Part Number: LMR38020-Q1 Hello expert,
Could you have to check are there any limitation on using LMR38020-Q1 to make 12VIN to 1.8VOUT (2A). Fsw=1.5MHz? The schematic is shown as the following.
If there are some advices on design for CISPR25 CLASS5 EMC…
Part Number: LMR38020 HI
VSUP_POE : 37~57V
VOUT : 34V
1. When input voltage is applied to the LMR38020, it initially outputs 34V then gradually decreases over time (under no-load conditions). Can you tell me why?
2. When a load is applied while the voltage…
