Hi, Jose,
DRVLIM will MOSFET power limit, could you please check the MOSFET temperature using thermal imager to check whether there is over temperature protection?
EN is a input signal determined by you setting signal. We need to check EN input source…
Part Number: PMP4334 Hi everyone,
I have two questions for you regarding the circuit in this reference design (PMP4334). The first one is regarding the linear regulator composed by Q1, ZD4 & R17. The circuit is just there to keep the voltage regulation…
Part Number: PMP4334 Please help to share design files (schematic & PCB layout) for customer to modify design according to their requirement.
Have copied customer in the thread.
Part Number: PMP4334 Hi,
regarding the schematics for the PMP4334, I've noticed that Q1, ZD4, R17 are not assembled in the CBA. My question comes regarding how much would I need these components if I have dimming implemented for the LEDs. On the datasheet…
Part Number: PMP4334 Hi everyone,
Could you please let me know which flyback transformer is being used for this design (PMP4334)? On the schematics I could see that T1 (flyback transformer) has as PQ3230. The problem is that this reference takes me nowhere…
Part Number: PMP4334 Could you help to recommend best fit reference design with Multi output 50VDC/2A, 24VDC/1A, 5VDC/0.5A and Input: 90 to 265VAC (Universal Input) ?
Part Number: PMP4334 Hi,
I've come to a point in which I would need an equivalent part to the T1 on the BOM from the PMP4334. The part in question is a flyback transformer (PN: PG1266NL). The information online about this part are almost null. I have…
Part Number: PMP4334 Hi everyone,
thanks for spending some time have a read here. I was analyzing the schematic of the PMP4334 when I noticed some components (e.g. R32, R34, Q1, ZD4,...) which are stated as N/A on the BOM list but are seem to be present…
Other Parts Discussed in Thread: UCC29950 , LM3463 Hello team,
I am looking for a solution recommendation for the following specs:
Input Voltage : 85 - 305 VAC Output Voltage : 56 VDC / 120W Careabouts : low cost, space (size similar to or smaller than PMP4334…
If you open TI-Designs and filter by lighting, then refine the search with the keywords "Flyback" and "LED", it gives 55 possible results, with different specs/ratings:
