Boost converter
Hi I am using MT3608 boost converter to boost 18650 3.7v (2600mah) battery voltage to 9v. how do I know how much max current I can draw after boosting to 9v (battery is rated for 1c discharge) is there any formula to calculate it? I know converter can support max 2A but does that mean I will get 2A at 9V after boost? here are the details of …

Temperature Coefficient of a Photovoltaic Cell
Alternative Energy Tutorial about the temperature coefficient of a photovoltaic cell as pv cell temperature has a direct influence on its power output At a standard STC (Standard Test Conditions) of a pv cell temperature (T) of 25 o C, an irradiance of 1000 W/m 2 and with an Air Mass of 1.5 (AM = 1.5), the solar panel will produce a maximum continuous …
Voltage and max current of digital output?
i didn''t see the specifics and Google search isn''t helpful. I probably didn''t use the right keyword. So what are the typical voltage level and max current of the digital output? I wanted to get optimal resistor value to drive LEDs using this old formula: Vsource-2.2/.02 (voltage source minus 2.2v for LED, divided by 0.02A) Blue, purple, and white …
TP4056
What is the maximum current that I can get out of Output +, Output - pins. If I use the battery directly to my load I guess I can get up to 3Amps as battery has 1C capacity. Will it be the same from Output +- …
batteries
If you "forget about" internal resistance, then the maximum current is infinite. An "ideal" component, non-existent in the real world, can provide mathematically "pure" infinite or zero amounts of resistance, voltage, current, and all …
MPPT Solar Charge Controllers Explained
What is an MPPT or maximum power point tracker? A maximum power point tracker, or MPPT, is basically an efficient DC-to-DC converter used to maximise the power output of a solar system. The first MPPT was invented by a small Australian company called AERL way back in 1985, and this technology is now used in virtually all …
