4.4V TO 105V INPUT SYNCHRONOUS STEP-DOWN REGULATOR DELIVERS OUTPUT OF 1V TO VIN

The LT7101 synchronous step-down regulator from Analog Devices is a high efficiency, monolithic synchronous step-down dc-dc converter. It uses a constant frequency, average current mode control architecture and operates from an input voltage range of 4.4V to 105V and provides an adjustable regulated output voltage from 1V to VIN while delivering up to 1A of output current. The LT7101 offers high-frequency o ...

HOMEBREW DMX-CONTROLLED RGB LED LIGHT

This project is a small DMX-512 controlled, color-changing RGB LED light. The light can be controlled via the DMX512 protocol or it can run a number of built-in programs depending on how the software is configured. The light incorporates an advanced 16-bit PIC24 microcontroller with PWM capabilities, a 3D printed enclosure, a laser cut acrylic lid, a custom switching power supply, and a MEMS oscillator. The ...

How to Select a Voltage Regulator

All electronics projects need power. Power can come from either stored energy in a battery, or directly from mains AC voltage or DC power from renewable sources such as solar energy. Power Management ICs (PMICs) help manage the power requirements in a system including scaling voltages, battery charging, and DC-DC conversion. Choosing the right PMIC can make a difference in whether the final product becomes ...

Vehicle Battery monitor on a automotive relay form factor

Battery monitor on a automotive realy form factor Hi all! I’m really busy this year so I can’t post all the projects where I’m involved. Here’s one of the design I do last year for a client. He wants to measure the voltage of a car battery and set a couple of alarms when voltage falls below a defined values. Also, he wants to put the device in the relay box of the car, so the design needs to have a relay fo ...

Wave player using PIC18F4550 microcontroller

Making an audio player (.wav files) using PIC microcontroller is not complicated especially when the MCU has a PWM module. This topic shows how to build an audio player using PIC18F4550 microcontroller where the the file is stored in an SD card with FAT16 or FAT32 file system. In this project I used a wave file with sample rate of 16000 Hz and 2 channels (stereo). The file I used originally it was an MP3 fi ...

5V Power Supply Atop a 9V Battery

I have a $500 Rigol DP832 programmable triple-output power supply sitting on my bench, yet I built a 5V regulator to sit atop a 9V battery for some reason. Perhaps it’s more portable, or cheap enough to toss in with the rest of the project it is powering, or maybe the bench power supply is just overkill. Or maybe, just maybe, I saw other people making them and I thought it would be cool to build myself. Two ...
