How to make dc/dc converters rugged
Design standards for rail transportation equipment are so severe that they are used as qualifications for products targeting other areas where ruggedness comes in handy. Here’s a quick overview of what these standards entail. Martin Tenhumberg | Traco Power In transportation, there is an emphasis on electronic systems in rail because of expanding safety, telemetry […]
Low-power isolated, regulated dc-dc modules cover 35 to 120 W
Power density, low weight and ease-of-use are critical considerations when designing isolated, regulated dc-dc converter systems for a broad range of robotics, UAV, rail, communications and defense/aerospace applications. The new DCM2322 ChiP family, a lower-power variant of the Vicor DCM3623 series, are targeted to meet these important requirements. Packaged in a 22x23x7-mm ChiP, the new […]
Active 20-A 40-Vdc EMC filters provide MIL-STD voltage surge, spike protection
The TDK-Lambda FQB series of EMC filters have a rating of 40 Vdc at 20 A. Voltage surge and spike protection for dc-dc converters is accomplished through the use of active technology. The FQB has a rugged encapsulated quarter-brick package with a choice of flanged or non-flanged baseplates. These modules are suitable for use in […]
Interface controllers compliance with IEEE 802.3bt help deliver 90 Watts of power to applications
Using the new IEEE 802.3bt standard, Power over Ethernet (PoE) can be used to deliver high-speed connectivity up to 90 W of power over Local Area Network (LAN) connections. ON Semiconductor’s solutions not only support the new standard power limit, but extends it further to 100 W for systems including telecommunications and digital signage. The […]
Single-stage quasi-resonant flyback controller drives LEDs
Infineon Technologies AG releases a new LED driver IC to its XDP portfolio. The XDPL8210 is a constant current flyback IC with a high power factor and primary-side regulation. Key advantages of designing with XDPL8210 include outstanding functional performance for efficient designs as well as low bill-of-material (BOM) for small system cost and high flexibility. It enables excellent […]
