Part Number: LM2704 I developed the schematic based on the datasheet instructions but on testing it does not step up the voltage to 12V. I checked the Feedback voltage and it's 416mV. Therefore the output at the Schottky diode does. The Schematic is attached…
Part Number: LM2704 Hello.
I am a newbie in DC/DC design, so have some problem with LM2704. Design requirements: Input voltage -- 3,3 V Output voltage -- 12 V Output current -- 40 mA max. Output load -- 2 relay coil, 20 mA per one. Main purpose of this design…
Thanks, we have been using that tool. Switch freq is at 650khz with 86khz crossover and 56 degrees phase margin. So I'm pretty sure low phase margin is also not the issue.
We have the Current sense resistors wired as shown in Figure 9.2.2 in the LM27403…
