Other Parts Discussed in Thread: LM43600 Hello,
I've recently changed my buck switching regulator to an LM43600. The issue I'm having is that it doesn't seem to increase the duty cycle under load. I'm kicking of a Tiva Arm and ADC and this…
Other Parts Discussed in Thread: LM43600 I have implemented a WebBench design of the LM43600 with +24VDC input and a +12V output with .5A max load. The circuit starts up correctly most of the time. But when starting cold there is an occasional instability…
Other Parts Discussed in Thread: LM43600 , LM5015 I'm working on a design where the LM43600 step-down is on the secondary side of a flyback.
To reduce ripple currents and noise in general (the board includes some precision ADCs etc.), it would be nice…
Other Parts Discussed in Thread: LM43600 Hi,
My customer is using LM43600. He has a question about the relation of Vin-min-st and Vin.
Vin-min-st value is showed as max 3.8V in datasheet. But this device can operate from Vin=3.5V (min).
Could you let me…
Other Parts Discussed in Thread: LM43600 , LM43603 Hi,
Will the LM43600 sync up with a spread spectrum clock source? I was looking to spread the clock over the range of 1.8 to 2.2 MHz.
Thanks,
George
Other Parts Discussed in Thread: LM43600 Hi,
I designed in LM43600, but the parts of the datasheat can't be used.
The condition is 12Vin 5Vout 0.5A 500kHz.
Datasheat is 33uH,66uF but Webench is 47uF,22uF and can't select ceramic capacitor.
Which…
Hi,
Yes according to the datasheet it seems to be ok to keep the EN pin floating.
Another alternative is to use a part where EN can be tied directly to VIN such as
LMR23610-q1 or LM43600-Q1

Use LM43600 for your application . You may design the circuit using Webench online .
Further first order Evaluation module for the desing and implement your circuit my modifying the EVM .

I do not generally support applications with output current that low. You could use a 2 or 3 A rated device but that is overkill.
For the -3.5 V output Webench suggests LM27761 or LMZ34002.
For the 1.8 V output, Webench returned a large number of possible…
Other Parts Discussed in Thread: LM43600 I'm using LM43600PWP evaluation board to step down my output voltage. The input voltage is expected to be something between 4-12 DC volts, and the output voltage should be 3.3V. The output of this buck converter…
