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…
Other Parts Discussed in Thread: LM25575 Hi,
I used the National Webench Power Architect to put together a power supply, and the tool recommended a LM25575 for the 5V rail.
My input is from a rectified 24VAC source.
Without a load or very little, Vout…
