  • Forum Post: Negative voltage generation with DCV010512D

    jean-michel herve
    I designed a board with 2x DCV010512D to generate +24V and -24V. For the +24V, no pb it works fine. But for the -24V, I mesured ~-4V: I connected the input on 0/+5V. The +Vout is used as ground reference and -Vout as -24V. I loaded the outputs with 1uF capacitor and 10kohm resitor between...

  • Forum Post: PTH12050 inefficient load

    Chris S.
    I am currently using the PTH12050 to create +5vdc on one of my products, however there is not enough load to run it efficiently. I only draw a couple hundred mA, where this module is rated at 6A with efficiency rating 93% at 5A/5V. I have had a few modules burn up. Any suggestions?

    Why is it that the PTH04T260 DC DC converter is qualified for MIL-STD-883D and not for MIL-STD-810F which also is for mechanical vibration

    luc Balsacq
    Let me explain in other words: we currently produce and deliver to USA a communication product that was certified NEBS level 3 for years. Recently, due to lack of availability of the previous PT series (e.g. PT6643E and many companions), and upon distributor's advise, we made a mid-life update...

  • Forum Post: DCP010515DBP incorrect output

    Kamran Rezaei
    Hi, I used a DCP010515DBP with Cin=2 uF ceramic and Cout=1uF ceramic to supply two components, one is LA 25-NP that is a current transducer with +/-15 Vs and the other one is AD202JN that is an isolation amplifier with +15 Vs. I want to use these sensors to sense the input voltage and current of a...

  • Forum Post: PTN78000AAH Maximum Output Current and Temperature Derating

    Dominique Megran
    Our product uses a PTN78000AAH voltage regulator module with a 24V input and a -15V output. I have discovered that the regulator is supplying approximately 0.75A continuously. The datasheet maximum output current is 0.6A at -15V with an ambient temperature of 85°C with natural convection airflow...

  • Forum Post: DCV010515D Output Power

    Mateus
    Hello, My question is if the 1W output of DCV010515D is limited in 0,5W to each output (+15V or -15V) or shared in any proportion (P@15V [0,8W] + P@-15V [0,2W] = 1W) ? Regards, Mateus.

    Matt Flax
    Hi there, I have a working 12 to 24V switcher @ 2.5A using TPS40210 - using TINA I can test it and it looks good ! I would now like to create a 12 to -24V switcher @ 2.5A. I have tried using the LM5088 however it appears to oscillate from -22V to -1 V, rather then hold -24V constant (circuit screenshot...

    Hello All, I have a customer who is using this to generate core voltage for their processor. On this design, over a hundred boards have been produced and >50% of them exhibit failure very intermittently over hours of operating time. It took a long time to try and capture the failure mode - a power...
