Part Number: LM5145-Q1 Other Parts Discussed in Thread: LM5145 Hi team,
This is Venu Gopal.
I have an issue with IC LM5145-Q1. I have five DC-DC converter circuits in series on a PCB which are designed for 24V and 8A each. This each Converter output again…
Part Number: LM5145-Q1 Other Parts Discussed in Thread: LM5145 Tool/software: Hello sir,
Could you help to show how to calculate LM5145-Q1 loop response?
Part Number: LM5145-Q1 Other Parts Discussed in Thread: LM5145 , LM5146 Dear Team,
Previously I have asked few questions on the LM5145 IC, and we performed testing all most all the issues. Now I have prepared new layout as per guidelines given in the datasheet…
Part Number: LM5145-Q1 Dear Team,
First of all, thanks for the continuous support.
Sir this is the circuit I made, and we have prepared layout as per the guidelines and PCB fabrication and assembly completed. I have 3 similar circuits on my assembled…
Part Number: LM5145-Q1 Dear Team,
First of all, thanks for the continuous support.
Kindly find the attached Schematic file below for the reference. I am getting my expected output voltage of 24V with little bit variation, which is in milli volts, but…
Part Number: LM5145-Q1 Other Parts Discussed in Thread: LM5145 Tool/software: Hi team,

Thanks a lot for your time and effort…
Hi David,
Looks like I missed your reply.
The low-side FET adds to the total switch-node capacitance, and this is effectively switched by the high-side FET, so the high-side FET has increases losses when the low-side FET is capacitive. See the loss…
Part Number: LM5145-Q1 Hello sir,
We used LM5145-Q1 for first level power supply design.
Vbat=12V (typical), VOUT=3.3V, IOUT=14.4A, FSW=250KHz, how to calculation IC LM5145-Q1 power dissipation for thermal simulation?
I used WEBENCH to simulate and there…
Part Number: LM5145-Q1 Other Parts Discussed in Thread: LM5146 Tool/software: I have design buck converter (LM5145-Q1), input voltage is 54V and output voltage is vary from 1V to 10V by adjusting feedback resistor at max.8A load. I am getting expected…
