DPA series is specified for 75V DC input maximum. From the block diagram, only L pin seems to be influenced by this input. Can we somehow manage the Lpin so that the input voltage range can be extended to 85V DC.

Hello, what is the minimum turn on voltage of the INN3977CQ? We have a product that requires a galvanically isolated converter from 16-30VDC to 15V/0.5A with 5000Vrms. Is an external supply (as in DI-152) required for the BPS pin? Thanks

Hello, Using LNK3694G part with EE13 size transformer. Overall design works but during operation I've observed high Vds peak voltages (possibly due to leakage inductance?). Any recommendations for transformer winding/layout adjustment to reduce leakage inductance? Would bias-sec-pri or pri-bias-sec would reduce leakage inductance significantly ? In existing design replaced RC

Hi, may I know about the design life time of the gate drive core? It is related to our product life cycle manage. We get some cores from the agency's stock which was produced 5 or 6 years ago.

Hi, In PI Expert Online Tool, There is a term Transformer fit estimate 48% . What is meaning of this term? Is it related to core or Winding area? what It shows occupied area or probability of wiring? Thanks.

There was a wiring error on EN/UV pin, sorry for bothering you Best regards, KK

Hello. The customer has a requirement for a power supply that must be very flat (the populated PCB must not exceed 10.5mm). 230V input, 24V output, 15W continuous power and 60W short term (max 3 seconds, max 5% of the time). I thought I might base this on the sample

Hi I saw that the LinkSwitch LNK3696 embedded a 900V MOSFET. I'm looking for an alternative SMPS with 100V-480VAC +/-10% input and one 12VDC/0.6A output for industrial use. Can the LNK3696 be used? The circuit needs to be isolated by using an auxiliary winding in the primary side of the

Datasheets of 1SP0335 gate driver series introduce Dynamic Advanced Active Clamping(DA^2C) to suppress High Voltage during IGBT switching events. I ask you to answer these questions about the 1SP0335 gate driver DAAC function. 1. Does DAAC function perfectly control (or cut away) high voltage over threshold voltage of each gate

Hi all, has Power Integrations ever used a painted dot to mark the first pin? Is this LNK364PN IC genuine?
