- EDN Under certain conditions, ESD events can damage digital circuits by causing latch-up. For example, when ESD triggers them, parasitic transistors normally formed as parts of a CMOS device can behave as an SCR (silicon-controlled rectifier). Once ...12-10-2020
- EDN Many power-supply designers like to have a regulator latch off in the event of an overcurrent situation or other fault condition. Yet, many PWM controllers do not internally support this latch-off function. Most do, however, have a power-good ...08-10-2020
- EDN Texas Instruments' UCC3895 offers a good base for building a high-efficiency, pulse-width-modulated, switched-mode power supply that suits either current- or voltage-mode control. Designed for driving a full-bridge power inverter using two ...06-10-2020
- EDN The battery monitor circuit in Figure 1 can be very helpful for any portable equipment powered by two 9-V batteries. When both batteries are in good health, an LED produces short bursts of light every second. If either or both batteries drop ...24-09-2020
- EDN If you use an ADC to monitor a system's power-supply voltage, you may encounter situations in which the supply voltage exceeds the ADC's reference voltage (Figure 1). However, the ADC's input voltage cannot exceed its reference ...17-09-2020
- EDN This Design Idea presents a self-powered, precision-active-load circuit that improves on a previously published design (Reference 1). Added features include a wider operating-voltage range of 2 to 50 V or higher and several flexible ...10-09-2020
- Jui-I Tsai, Woei-Wu Pai, Feng-Chang Hsu, Po-Jui Chen, Ching-Cheng Teng, Tai-Shan Liao EDN Most laboratories and industrial environments have many kinds of electrical-noise sources at all frequencies from heavy machinery, instruments, power ...10-09-2020
- Christian Rausch EDN Designers use ballast ICs, such as International Rectifier’s IR53HD420 , in CFLs (compact fluorescent lamps) for heating the filaments, igniting the lamps, and supplying the lamps with current. Manufacturers produce these ...02-09-2020
- Thomas Brand Analog Dialogue Question: How could I use a digital potentiometer to generate an adjustable voltage output? Answer: By using a push-button digital potentiometer. This article describes a complete solution in which a voltage up to 20 V ...27-08-2020
- Michael Fisch EDN Laser diodes are sensitive to ESD, rapid turn-on currents, and overvoltage conditions. To address those problems, the simple laser-diode controller in Figure 1 has several functions. The first part of the circuit comprises an 8.2 ...27-08-2020
