Other Parts Discussed in Thread: LM25018 Dear sir/madam,
I designed a 24V-5V isolated power with LM25018, but its output will drop by 1.2V when 200mA load is connected to output. The output voltage is 5.9V when output is float, but it will drop to…
Part Number: TIDA-01093 Other Parts Discussed in Thread: LM25018 , Hi Champs,
could you explain how the power supply works on this design? I see the LM25018 being placed between between BAT+ and GND_B but how do we ensure that the voltage is limited to <48V…
Hi Han,
Q1: I-HSCL is the high side switch current limit, 2.75 A typical, 2 A minimum
Q2 and Q3: Do not use any design equations from LM25018. LM25018 is a non-isolated buck converter. Use only the design information from the TPS55010 datasheet.
Part Number: TIDA-01093 Other Parts Discussed in Thread: ISO1050 , LM25018 , , BQ76930 , BQ76940 Dear TI experts，
As is shown in reference design(tida-01093), the supply voltage of iso1050 CAN transceiver is 5V, so LM25018 regulator is needed to offer the…
Hello Stefano,
I repeated the same range again in the Webench and I got the same issue again (exceeds current limit). See attached.
I used 10-14 as VIN, 3.3V@120mA as VOUT1 and 6.6V@130mA as VOUT2. Checked the isolated output option. Of course it just…
Other Parts Discussed in Thread: LM25018 , ISO3080 , ISO3082 Hi,
I’m currently working on a new board design that uses TI component ISO3080DWR. Due to tight space constraint, I am considering placing this component on the bottom side of the printed circuit…
Dag Bert,
have seen your conversation in the e2e Forum:
Maybe you can have a look at LM25018 used in a fly-buck topology. In case of using 2 windings you can support pos and neg isolated outputs.

Hi,
The secondary regulation (VCC+ in this case) requires that the part be in CCM (continuous conduction mode). This means that the inductor current (primary winding) should be continouous (you should check this on osc). This only happens in a non-synchronous…
Other Parts Discussed in Thread: LM5017 , LM5018 , LM5019 , LM25017 , LM25019 , LM25018 Hello,
I am designing a data logger for 16 sensors, and I need to power sensors separately from isolated power supplies (each supply must be isolated from each other).

Hi Kamal,
The LM25019 and LM5019 product webpages have Webench and an excel based quick-start calculator tool.
