Power management

I was using L4985A in my boost converter circuit. I was observing abnormal current spikes in input current waveform and audible noise is coming in no load condition itself, same in load current.Current spike coming every few seconds?

Boosting operation starts at 80Vac.It is working fine and voltage is boosted to 400Vdc as per design. Please refer the attached Input current current and duty waveform in no load condition, schematics.

How can I get data on TS3021ILT quality reliability level ?

We have purchased STeval_TTM001V1_Automotive_5kW. We have few queries related to it. 1. Increase the overvoltage limit from 36V to 48V or 60V? 2. How to enable the overcurrent protection 3. Load consumption of 5V and 3V3 supply?

1. What is the detail procedure to increase the overvoltage limit from 36V to 48V or 60V?2. How to enable the overcurrent protection as by default its disabled.3.What is the load consumption of 5V,1A and 3V3,1A power supply supply by STeval component...

Stdriveg600: not available in the market

Hi there,​I'm doing my Master's thesis and using Stdriveg600 in my design. However, I just noticed that it's not available in the market. ​Is there any way I can get 6-8 units of​ Stdriveg600 within months? My thesis is about to end soon and I need t...

Using the SRC0GS22D, the datasheet is unclear as the which part the SRC0GS22D or the SRC0GS225 has an high Enable when active.

Nucleo boards get fried as soon as I connect charger to my MacBook Pro

After working a while with a brand new Nucleo WL55JC1 (power jumpers untouched) connected to my MacBook Pro (2017), my laptop battery was empty and I connected the charger.Charging behaviour was strange, laptop switched from "charging" to "not chargi...

"Class D" Inverter?

I need a 100 kHz, sinusoidal AC constant-voltage power supply, feeding an inductive load. Can i make a power inverter designed like a class D audio amplifier.  Except, instead of a speaker, it's a hungry power load that wants up to 20A, 5V AC power. ...

Hi, Was wondering whether it would be possible to inquiry about the failure rate (FIT/MTTF/MTBF) for SMA6F (SMA6F5.0A), is such information available? Thanks, Christopher

TS33 datasheet mentions that it supports 1.8V fixed output voltage too, but cannot find relevant ordering code.

T435-600B Issue with Solenoid Pump and diode

Hello everyone,I'm currently facing an issue with controlling a solenoid pump using a triac T435-600B in a configuration that includes a diode. The power supply for both the triac and the pump is the same, and it's triggered by an opto. I am unable t...
