Part Number: LMR12015 Tool/software: Hi all,
When the input power is turned off by LMR12015, the following peak current flows through Vin on the waveform shown on the right.
This current is about 2.3A.
When the power supply is cut off, the margin…
Part Number: LMR12015 Hi All,
I have a question about Feedforward Capacitor.
The formula below does not match the capacity of the CFF in Figure 37. Are there any other conditions or recommended capacitor capacities?
Also, depending on the…
Part Number: LMR12015 Hi All,
I have a question about LMR12015.
(1) Please tell me the min value of OVP. Also, what is the automatic recovery time after OVP operation?
(2) Is there a graph of Minimum Load Current for L = 3.3 µH when VOUT = 12V…
Part Number: LMR12015 Hi All
The thread was locked, so I'll post a new one. I have a question about LMR12015.
I would like to know the minimum load current value under the following conditions. - VIN=15V - VOUT=12V - L=3.3uH
I referred to "7.3.3…
Part Number: LMR12015 Hi All,
I have a question about LMR12015.
Although it is a 12V output, the output will be 3V because there is no load. Minimum load current is required from "7.3.3 High Output Voltage Considerations".
If you continue to output…
Part Number: LM27341 Other Parts Discussed in Thread: LMR12015 , Currently there is a very long lead time on the LMR12015. Can the LM27341 be used as a direct replacement? I have read through the two datasheets and cannot see obvious difference between…
Hi Luke,
I'm happy to see your design is working a expected.
The diode can affect the performance in multiple ways, and yes improperly sized diodes will cause device failure. Let me explain:
The diode has two parameters of interest. The voltage…
Hi
I am still working on tying to solve this failure problem. I have conducted tests to ensure there are no transient spikes on the input pins, and have relaid the PCB with better solder past and via arrangement. The part is still failing.
The failure…
Other Parts Discussed in Thread: LMR12015 I am using the LMR12015 to convert 9V from a 9V battery into 3.0V. The LMR12015's AVIN (analog supply input), PVIN (power supply inputs) and EN (enable) inputs are directly tied to the 9V battery voltage. Here…
Other Parts Discussed in Thread: LMR12015 , LMR12020 , LM27341 , LM27342 Hello,
Working with the customer on the LMR12015 and LMR12020 and they have requested Altium Designer CAD files for these devices. At a minimum, they need the Altium schematics…
