Other Parts Discussed in Thread: LM25575 , TPS54540 Hi,
I have a TPS 54540 to generate +15 VDC from 28VDC and in the cascaded structure, I have used LM 25575 to generate -15 VDC from +15 VDC. I do like to synchronize both power module to an external CLK…
Other Parts Discussed in Thread: LM25575 I used WebBench to design a -5V supply
it generate a circuit for -5 output using a LM25575, currently having issues getting >5ma out of this configuration It is rated for 500ma.
Other Parts Discussed in Thread: LM25575 , LMZ14203 We use LM25575 in an inverting design to generate -11V from 12V input.
The webench design doesn't show where to connect the exposed pad (EP).
Where should EP pin connected to GND or Vout (-11V in our…
Other Parts Discussed in Thread: LM25575 We use multiple DC-DCs and one of them (LM25575) doesn't shutdown properly.
We use the LM25575 to generate a Vout=-11V from a Vin=12V. The SD (Shutdown) pin is controlled by a transistor from a microcontroller…
Other Parts Discussed in Thread: LM25575 Hi
We have designed a couple of power supplies (±7.0VDC/0.70A) based on the LM25575 device. The power supplies has been based on output from the Webench tool. The schematics is attached for information.

Other Parts Discussed in Thread: LM25575 , LM5575 > Hello,
I have made a board using different LM25575 to manage the power supplies from a PLC backplane providing 24Vdc as shown herebelow:
- A first stage converts 24Vdc to 5Vdc,
- A second stage generates…
Other Parts Discussed in Thread: LM25575 Hello,
I am designing a +/-12VDC supply based on LM25575 converters used in cascade. The topology consists to create a +12V from 24VDC (coming from PLC backplane). From the +12V we create the -12V by using the LM25575…
Other Parts Discussed in Thread: LM25575 , TPS54061 Hi,
I have a voltage requirement of -18V at 200mA with +12V as the input. When checked with the WEBENCH tool, LM25575 appeared to be a solution.
Can -18V be obtained from +12V using a buck regulator.
