    Struggling to fix voltage drop in my LED circuit

    My goal is to power 600 WS2812B RGB LEDs at full power. Currently, when all LEDs are set to white (255, 255, 255) at max brightness, a color gradient from white to red is displayed. I discovered that this also happens when, for all LEDs at max brightness, any one RGB channel is maxed out and...

    FoM for power consumption on a transistor level

    Hello Everyone, I am fairly new to this so please bear with me. I have been looking at reducing the static power consumption in an IC, and have been mainly focussed to reduce the parasitics in the wiring in the BEOL. However, I was wondering that whether in the FEOL, on an n-type transistor...

    Battery powered led challenge about power consumption

    I have an easy project but if you have enough experience about it. -I have a led which typical forward voltage 2VDC and current value is 20mAh. -I need to drive this led at the different brightness levels. And the levels will be changed by pushing a tact switch. And I have to lock tact switch by...

    Facing an unexpected voltage drop across output

    Hello all, I am using a Step-Down Converter (Part Number: TPS543C20RVFT from TI) set up in a Two-Phase Master-Slave configuration on board. I feed the input of 5V and expect 0.85V at the output. During startup, the requirements are met, but after configuring the program on the board, I am...

    power consumption esp8266 diagram

    hi everyone, I'm interested to know what software or hardware you can build such graphs for consumption, bootloading or starting the firmware, performing any operations, and power consumption for esp8266, I have seen several diagrams like this on the internet. and they are designed all...

    Why Power supply have unreasonable no-load input power consumption?

    Hello all, I have a SMPS power supply based on the TNY276 PMIC, I did a "No-load input power consumption" test using DMM connected to AC line input to measure current values while varing the input voltage from 85VAC to 265VAC... I got the following results: Input Voltage (VAC) Input...

    Energy Consumption

    I have a fan with three different speeds. On the bottom it says that it uses 43 watts. Does this value go to the slowest speed or does it always use the same amount of electricity.

    Which power supply to use for Raspberry Pi?

    As far as the official specifications are concerned an rPi can be powered with supplies from 5V to 12 V. Typical current for 5V supply is 2A. Total power required for an rPi is 10W roughly. I have two power supplies (5V, 2A) and (10V, 1A) which one to be used so that the pi dissipates less...

    Darlington transistor POWER AMPLIFYING

    Hi all, I just couldn't find the answer on web so I had to ask you guys. Based on my understanding, input power is ideally equal to the output power of a circuit unless it is dissipated to heat. So I was looking at the ULN2003 Darlington controlling a 28byj-48 stepper motor using an Arduino...

    Electrical switch for a non-chemical battery - How to do it?

    Hi everyone, I’m seeking guidance. I have a tricky situation which I don’t really know how to get out of. I want to design a system which would consume the least amount of power possible. The idea is to have an ESP8266 do a simple task every minute (updating a e-paper display) and sleep the...
