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
