TDK-Lambda selector tool features dedicated Vega AC-DC power supply configurator TDK Corporation has introduced an upgraded TDK-Lambda Rapid Selector which replaces a parametric search wizard to enable designers to select from a total of more than 3000 different Vega AC-DC Power Supply configurator program. The selector now covers all product ranges,” explained Paul Goodwin, Product Manager at TDK-Lambda EMEA. The Rapid Selector also brings some enhancements relating specifically to the Vega range of configurable power supplies; these include: Quick configure will now offer Vega units if these are appropriate (for both AC input and DC input). View configured product: - automatically show results for both Vega and NV products - single-step process (enter the part number, click view) Configure a Vega (previously this was only available on the Vega stand-alone configurator program) Request a quote from the offered results All features available on desktop or mobile devices In addition, series connected ‘C’ modules for NV350 and NV700 are now available from 48 V up to 64 V. The TDK-Lambda Rapid Selector can now select from a total of more than 3000 different AC-DC and DC-DC products from over 100 different product ranges. In addition, the configurable/modular products range is offered. TDK Corporation uk.tdk-lambda.com www.electronics-eetimes.com Superior Solutions for Industrial. Aluminum electrolytic capacitors up to 600 V PFC products for energy saving and power quality EMC and sine-wave filters for currents up to 8 kA X and Y capacitors for EMI suppression Common-mode chokes for high currents Varistors and surge arresters for overvoltage protection Power electronic capacitors with high reliability High-current chokes for power supplies Various types of MLCCs for highest reliability Rare earth and ferrite magnets SMT power inductors with high reliability Large ferrite cores www.tdk.eu · www.epcos.com AC-DC and DC-DC products; additionally combining Vega and NV configurators. “The most important, recent change with the introduction of the upgraded Rapid Selector is to integrate the dedicated Step-down switching regulators with built-in 800mOhm power MOSFET Rohm Semiconductor’s BD9G101G series of step-down switching regulators feature a built-in 800mΩ power MOSFET and provides a 0.5A DC output with excellent line and load regulation for smart power management, in a small SOT23 (SSOP6) package. The operating frequency is fixed at 1.5MHz, allowing the use of a small inductor and a ceramic capacitor in order to reduce space requirements. All phase compensation components are integrated as well. The input voltage can vary from 6 to 42V, the internal reference voltage is set to 0.75V with an accuracy of typical ±1.5%. Suited to facilitate step-down switching designs, the new device offers first-rate thermal resistance and multiple protection features such as internal over current protection, under voltage locked out and thermal shutdown . The operating temperature spans from -40 to +105°C while the maximum junction temperature lays at 150°. Areas of deployment are industrial distributed power and automotive applications, battery powered equipment and medical OA instruments. Rohm Semiconductor Europe www.rohm.com
