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…
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.
It…
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 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…
Re,
I have mistake to join you a plot of the -12V potential:
All scopes have been performed with a differential voltage probe with a gain of 1/10.

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…
Other Parts Discussed in Thread: LM25575 Could anybody that has access to a board with a LM25575 switcher be so kind to measure with a multimeter the impedance between pin 13 IS (current sense) and ground and let me know the value read? I was expecting…
Other Parts Discussed in Thread: LM25575 , LM3100 , TPS54140A I'm using a LM25575 to deliver 3.3 Volts with a average load of 1A.
It's all ok, but if the load shrinks to aprox. 100 uA the input current is still 8mA.
Is there any possiblility to…
