App note: How to use power inductors

A great guide from TDK about power inductors used in DC-DC converters. As electronic devices become more advanced, the power supply voltage of LSIs used in them is lowered, so their power consumption can be reduced and their speed increased. However, a decrease in the power supply...

Bootstrap Circuit in the Buck Converter explained

This application note explains the step-up circuit using a bootstrap capacitor. In buck converters, this circuit is used when the high-side switch is the N-ch MOSFET. The configuration of the circuit in proximity to a buck converter depends on the polarity of the high-side switch.When...

I2C – Everything you need to know

I2C - Everything you need to know article from www.mikroe.com There is no need for a wordy introduction to I2C protocol. We all know it's main parts - 2 wires, multiple slaves, sometimes multiple masters, up to 5MHz of speed. Often so have we all implemented an I2C connection. Still,...

Use a Comparator or Op-Amp to Simplify Light Dependent Resistor Output

If your project calls for light sensitivity, it’s hard to beat light dependent resistors (LDRs), also known as photoresistors. They’re available for a few cents each, and their resistance varies based on how much light they receive. In the dark, these devices produce resistances in...

How to make precision measurements on a nanopower budget

Gen Vansteeg @ ti.com discuss about precision measurement for nanopower scale using OPAMPs. Heightened accuracy and speed in an operational amplifier (op amp) has a direct relationship with the magnitude of its power consumption. Decreasing the current consumption decreases the gain...
