we required 3.8V/4A with Inn3694c but ckt is not working properly. kindly advise.

I have designed a AC-DC power supply using TOP257YN with PI Expert 10. Now the device TOP257YN is not available however TOP258YN is available and we have a stock as well. Can I use TOP258YN without modifying the design or with a minor modifications to the design? The design is

The datasheet is a bit short on detail of the operation and characteristics of each pin. I would imagine that there is a dirty trick method of paralleling these devices and getting them to share nicely. Currently, the PFC method I use is very expensive being a 1600W module. If

Hello, I am trying to test the short-circuit protection feature of the 2SC0106T2A1-12 gate driver. I am using the circuit similar to the one mentioned in the application manual in page # 13 (see attached image). I use an external adjustable power supply connected between "Collector 2" and "Emitter 2"

Dear Sirs, I would like to know if the TOP222YN are still in production or not. Because I have 2k units with date code 2014 and I don't know if is a refurbished component. Please could anyone check if the date code are realible? And also I attached a photo

Hello, I've been looking into the DER 832 application example and I'd like to find a supplier for the Transformer. Would you be able to suggest one or provide some guidance where I can find one. Also would it be possible to adjust that application with active rectification on the

Hello, We are using a 1SP0635 gate driver to drive a Fuji 1MBI2400VC-120P. Due to availability problems we purchased gate drivers _without_ any gate resistors. Could you name recommended gate resistors for the aforementioned combination? Best Regards Norman Werner.

Hi Team, can you please guide me for designing SMPS with Vin range of universal or 85-300VAC or up-to as max Vin we can support ? i need UVLO detection and also protect SMPS from large VIN up to 1000VAC / max we can achieve . I need surge protection

I have to design SMPS with below specification :- Maximum AC input voltage 440 VAC Minimum AC input Voltage 85 V Switching Frequency 60-70 kHz Efficiency 85-90% Output Power (maximum) 10 W Main Output voltage 5 V AC Line frequency 50 Hz Output ripple voltage 0.15 - 0.25 V i

If safety agency applies a short-circuit between pins 1 & 4 of TNY276GN, EOS occurs at the detector of the optocoupler. Subsequently, the optocoupler suffers catastrophic failure caused by the rapid temperature rise and explosion which, in turn, compromises the DTI and the unit no longer passes Hi-POT. The fuse
