Tool/software:
Hello everyone,
Does the LM25018 include a schematic of the soft-start circuit? The datasheet only shows a standalone soft-start circuit, and I’m unsure how to connect it to the chip.
Thanks,
Ivy

Hi Ivy,
The part shown in the red box is the external soft-start circuit. The diode D should be connected to the FB pin and cap C1 should be connected to VCC pin of the device as shown. RFB1 and RFB2 are the feedback resistor dividers which will be present in the application circuit.

Hi Ivy,
The diode should be connected to the feedback (FB) node as shown.
