Search results: 459 Output: 31-40 Keith Szolusha EDN In certain dc/dc-converter applications, on-chip, cycle-by-cycle current limit may be insufficient protection to prevent a failure during a short circuit. A nonsynchronous boost converter provides a direct path from the input to ... 14-12-2016 Poonam Deshpande Electronic Design A basic combination of a photovoltaic panel, multiple LEDs, and a small dc-dc regulator can provide light in dark corners while also offering a modest auxiliary dc-power rail. A solar-powered, daytime-only lamp ... 14-12-2016 Bob Smith, Linear Technology Design Note 1036 Introduction The LTC®4370 is a 2-supply current sharing, diode- ORing controller that uses MOSFETs to form ideal diodes. In this way, the LTC4370 can actively balance the output currents of two ... 02-12-2016 Richard Dunipace EDN Low-cost DVM (digital-voltmeter) modules are economical and can significantly reduce design time for instrumentation. Yet, these modules also involve a significant number of design challenges. For example, their inputs are not ... 02-12-2016 Sajjad Hajdar Electronic Design Most common current-limiting implementations have a voltage drop that’s too high for today's systems with their low-voltage supply rails; this design with its far lower voltage drop is a better fit. There ... 18-11-2016 Peter Miller EDN Like other simple, single-cell lithium-ion battery chargers, Microchip’s MCP73812 provides no means of indicating the charging status. You can remedy this situation by adding four components (Figure 1). Add one more LED, and ... 24-10-2016 Keith Szolusha, Linear Technology Design Note 548 Synchronous buck-boost converters with four power switches can deliver very high efficiency while providing both step-up and step-down DC/DC conversion. Combining the capabilities of two separate ... 18-10-2016 Chee Hua How EDN This Design Idea demonstrates a way to adjust the output voltage of a power supply, for OVP/UVP testing, margin-testing the load, voltage programmability, or any other reason. The circuit in Figure 1 is capable of bidirectional ... 10-10-2016 JB Castro-Miguens, C Castro-Miguens EDN Protect circuits from high current until a capacitor charges A high-power offline supply is nothing more than a half- or full-bridge dc/dc converter. Rectifying the ac line yields a dc voltage that feeds the ... 10-10-2016 Steve Hageman EDN In the old days every instrument or system had a power supply board with discrete, homemade regulators on it to power the system. Then IC's like the LM7805 series of voltage regulators changed everything. No longer were system ... 27-09-2016
