  1. The added output has its own voltage regulation Designers use step-up-converter ICs in battery-powered portable equipment. These chips usually provide one output with a fixed or an adjustable voltage. Some chips contain an LBI/LBO ...

  2. Donald Boughton, International Rectifier EDN Eliminate errors caused by bias currents and temperature drifts Analog-circuit design often requires a constant-current sink. An example would be for a TRIAC (tri- ode-for-alternating current) dimmer ...

  3. Bob Zwicker, Analog Devices Many systems must select among two or more low-voltage dc-input sources, such as an ac adapter, a USB (Universal Serial Bus) port, or an onboard battery, for example. You can implement this selection using manual ...

  5. The following automatic battery-charger design is created with a circuit that could qualify as the simplest window comparator ever built around a single transistor. It starts charging when the battery voltage drops beyond a preset value, and it ...

  6. Alan Yates A lot of people have been asking me for the circuit of the demonstration TX I used in the video, so here it is: This is *not* an efficient design and is meant as a demonstration only. The compression trimmer should be fairly high ...

  7. By Keith Curtis Microchip Technology For a recent project, I needed a regulated 15-V power supply capable of delivering a couple of milliamps. But the raw supply voltage to the circuit was only 9 V, and I didn’t want to add the expense of an ...

  8. Recently I worked on a project where I wanted to control a servo using an Atmel ATtiny85 . I checked online for ready made code that did this but I couldn’t find anything satisfactory. Not wanting to switch to a larger microcontroller I ...
