AN5246 Application note How to use SMPS to improve power efficiency on STM32WB MCUs Introduction This document describes how the use the SMPS (switched mode power supply) integrated in microcontrollers of the STM32WB Series. It is intended to be used by system archite...
How to Do Sit ups - Sit-ups are a great way to keep your body toned and fit. They work your abdominal muscles, which are responsible for supporting your spine and keeping your posture upright. Additionally, sit-ups also work your hip flexors, which help

If it is a desktop, make sure that the power cable that connects the SMPS to the electric outlet isn’t faulty. If possible, try replacing it with a different one and see if the issue is gone. On the other hand, if you are using a laptop, check if its battery isn’t drained out...

Test the exit point from the skipping area mode at the nominal mains voltages to check that the system returns to the continuous switching mode below 75 W. Setting this parameter to "7" or "6" disables the skipping area feature, in case good THD and PF are required even ...
s original recommendation in 1975 is well documented (see “LTspice: Basic Steps in Generating a Bode Plot of SMPS”).1The actual signal injection location laid out in Middlebrook’s method is not commonly used these days but has been adjusted over the years, resulting in the commonly...
Be sure to generate a Bode plot with the design software and check the phase and gain margins, including over temperature. Problem #7: Low Efficiency The bootstrap capacitor needs to be big enough to provide charge to the high-side FET gate—otherwise, that FET might not fully turn on and...
Download Windows Speedup Tool to fix errors and make PC run faster The hard disk of your PC can take a hit if the power supply (SMPS) does not yield the desired output required for all the hardware and peripherals to function. This can lead to data corruption. During such instances, ...
I have some basic knowledge of SMPS voltage regulation feedback circuit concepts, and basics of control systems theory, mainly conceptually. I've hacked various PSUs and 5V battery chargers to make them variable voltage supplies. I'd like to learn some more about how power supply engineers det...
