Part Number: LMR36503-Q1 Other Parts Discussed in Thread: LMR36500
Tool/software:
I am designing a DC/DC converter to go from 30-60V input to 3.3V to supply about 20 mA to a microcontroller and some other chips. Efficiency is key, because it needs…
Part Number: LMR36503-Q1 Tool/software: Dears,
Please tell us how to calculate LMR36503-Q1 bootstrap resistor Rboot power disspation and its formula.
we need to know it to select Rboot size and power rating.
Thanks.

Part Number: LMR36503-Q1 Hi, LMR36503-Q1 is rated for 300 mA, but for my design, there are short (20 usec) current spikes that are 400 mA. Is that acceptable and not damaging to the part?
Thanks
Part Number: LMR36503-Q1 Tool/software: Hi there,
I am interested in the efficency of the 3.3V output version of this part in light load conditions (auto / PFM mode). Is there an equivalent to figure 7.3 (efficiency of 5V output part in Auto mode) but…
Part Number: LMR36503-Q1 Other Parts Discussed in Thread: LMR36503 , TPS62825 , LM25148-Q1 Team,
A customer of mine is currently verifying their LMR36503 design. Can you please help with following question?
On a LMR36503 design we measure up to…
Part Number: LMR36503-Q1 Other Parts Discussed in Thread: LMR36503 , LMR36506 Hello,
in datasheet of June 2020 there was detailed package information.

Part Number: LMR36503 Hi,
I am have downloaded the "LMR36503RF unencrypted transient Pspice model" from TI website and tried to run it in LTSpice. I have got a lot of errors as below:
Circuit: * C:\Users\user\AppData\Local\LTspice\LMR3650RF.asc

Part Number: LMR36503 Hello,
Our customer wants us to analyze the accuracy of his system over time. As he is using a MOSFET as a current (with a PWM), we need to know how the reference voltage (from the LMR36503) will drift over time (20 years).
Do…
Part Number: LMR36503-Q1 Hi Team,
I've found that on the ds page23 it's said that the device operation: FPWM Mode - Light Load Operation: Discontinuous conduction mode (DCM) when the load current is lower than half of the inductor current ripple
However…
Part Number: LMR36503 Hello,
I am doing accuracy analysis on my system that contains a LMR36503. I need to know how will be the line and load regulation when the temperature varys. Do you have any information about that?
Best Regards;
Aurélie D…
