Recently I need a power supply that supports outputting 300VDC, 250VDC, 150VDC and a combined power of 50W, the input could be AC or DC, I tried eDesignSuite but no result matched my need.
Dear all, The STSPIN958 contains all to build a digital controlled (hard switching) full bridge adjustable power supply, including the power mosfets, to my understanding. Or am I missing something important? If set as " Single full-bridge - PWM trimm...
Hi all,I am trying to design a power converter using the A69863V3TR and I am having some issues.I have followed the design section in the datasheet and used the online eDesignSuite to design a 3.3V DC/DC converter.The circuit has now been manufacture...
We are using the LD39200PUR as a regulator to step 5V down to 4.3V for a battery based system.The datasheet says the product incorporates reverse current protection to prevent current leaking from the output to the input but it is not functioning in ...
Dear Community,I'm a repair technician and I trying to identify a damaged component made by STMicroelectronics.Based on the surronding components and circuitry its a PMIC/DC-DC Coverter but I cannot find this specifc one.As you can see, all the infor...
We are currently using the ST1PS02BQTR for powering a compact main board with BT connectivity (STM32WB5MMG), an IMU, and other ancillary blocks (LEDs, charge pump for LEDs, passives). The system is powered through two AAA batteries connected in serie...
I’m trying to find a solution to create a PoE to 12V USB-C power delivery adapter as I can’t find one on the market. There are PoE to 5V USB-C PD ones, and PoE to 12V barrel plug ones, but nothing as far as I can tell that will provide the negotiatio...
We require a TVS or zener diode for a clamping application with high average power dissipation. LDP01-56AY does suit our needs, but the maximum average power rating is not described in the datasheet. Our application has an ambient of around 60 degree...
hi, I'm developing 48v 1kw.Is it possible to set the rising time within 50 ms using l6599ad?The datasheet uses Rss and RFmin to control the initial soft start, but it does not decrease to 400 to 500 ms at all. If you need a circuit diagram, I'll send...
Hello, I am having a problem with a design using the ST8R00WPUR.The input is 5v, the output is 10.5v, the load is 22 ohms (477mA).The problem is that the output drops below 3v for 200ms when the load is applied, before returning to 10.5v. The problem...
