What is an intuitive explanation on how a buck and boost converter transfer energy?
I can understand how a buck converter can step down the voltage but only with the formulas. I am struggling to understand intuitively how the inductor stores energy and releases it in a way so that ...

For a high powered LED loads, is a buck or boost converter more efficient / simpler?
I have a 3 high powered LEDs hooked up into a strip to for the load. For simplicity, I am going with a constant voltage driver. The load can be hooked up in 2 configurations:
Config 1:
3 Green LEDs (3....

Buck and boost converter inductor confusion
I have seen that a boost converter uses the spikes of an inductor to step up the capacitor voltage as this spike is stored on the capacitor.
Why don't we get a similar effect in the buck converter? A ...

Buck-Boost Converter Inductor Value
I am designing a typical buck-boost converter using the LTC3530EMS#PBF IC from Analog Devices.
My design specs are as follows:
Vin: 3.0V - 4.2V
Vout: 3.3V
Iout(max): 300mA
Fsw: 1MHz
In the datasheet, ...

MC34063A Poor load regulation in case of boost and buck converters
I'm using following circuit for a boost converter using MC34063A IC.
The circuit is designed for 24 V, 250 mA output. The simulation works fine but the actual circuit on a PCB behaves weirdly. In ...

DC current transmission loss vs. conversion loss
I'm going to transmit about 7 Watt DC over 4 meters long twisted pair Ethernet cable. I'm thinking of using Buck and Boost converters to step-up to 30 V and step-down to 5 V the voltage before and ...

Why my boost converter is not boosting the voltage?
I am trying to build a boost converter using LT3517 with 5V input. LED and input voltage(5V) is constant for our application. I need to tune the circuit between this and the current across the LED ...

What drawbacks to bucking, then boosting the same current?
Are there any real negative drawbacks - outside of the double drop of efficiency - of DC-DC boosting a power line that was already DC-DC bucked?
I'm building a modular system, serially linked through ...
