TPS61093-Q1 Low Input Boost Converter With Integrated Power Diode and Input/Output Isolation

Description The TPS61093-Q1 is a 1.2-MHz, fixed-frequency boost converter designed for high integration and high reliability. The IC integrates a 20-V power switch, input/output isolation switch, and power diode. When the output current exceeds the overload limit, the isolation switch of the IC opens up to disconnect the output from the input. This disconnection protects the IC and the input supply. The iso ...

How to control LM2596 buck-converter with microcontroller

Every now and then someone asks on different forums if there is an way to control cheap LM2596 modules with an Arduino or another microcontroller. I decided to demonstrate one solution that might be basic electronics for some, but still many don’t know about.Those buck converters will change the output voltage to make the feedback pin, connected to the output via a voltage divider, become 1.25V or so. If fe ...

NE555 timer sparks low-cost voltage-to-frequency converter

In 1971, Signetics—later Philips—introduced the NE555 timer, and manufacturers are still producing more than 1 billion of them a year. By adding a few components to the NE555, you can build a simple voltage-to-frequency converter for less than 50 cents. The circuit contains a Miller integrator based on a TL071 along with an NE555 timer (Figure 1). The input voltage in this application ranges from 0 to –10V, ...

Read analog values without an ADC using PIC12F675 microcontroller

Digital electronics and Analog electronics doesn't mix easily. A Microcontroller can't get analog values unless an Analog-to-Digital converter is used, however, you may find a little complicated the use of an ADC and it need lots of Input/Output ports.   Some Microcontrollers, like the small 8-pin Microchip PIC 12F675, do have an ADC integrated, but it is expensier than a PIC without ADC. A simple solu ...

Buck Converter (DC-DC)

Step 1: Gather the Materials! So with any prototyping project this really shouldn't be the first step... But we're gonna go ahead and do it cuz it's just so darn fun! Just a little disclosure, we'll be using the ACT4088 picked because it's cheap and has an adjustable VOut along with a max of 1.5A out. Of course if you need different characteristics chances are, there's a chip out there for you! The circuit ...
