Le contrôleur abaisseur synchrone, double phase, deux canaux, 65V de National Semiconductor permet de réduire l'encombrement des applications à tension élevée
National Semiconductor Corp. (NYSE : NSM) a présenté aujourd'hui le LM5119, un contrôleur abaisseur synchrone á tension élevée, deux canaux, double phase, à commande ECM (Emulated Current Mode, ou mode courant émulé). Le LM5119 permet la régulation de tensions d’une simple sortie ou double à forte intensité, à partir de tension d'entrées allant jusqu'à 65V, simplifiant ainsi la conversion CC-CC á tension élevée, tout en rédui...
New 10 Gbps Repeaters from National Semiconductor Double Signal Conditioning Performance at Half the Power
Extending its leadership in high-performance analogue technology, National Semiconductor today announced three multi-channel PowerWise 10 Gbps repeaters that provide the industry’s highest equalisation gain (36 dB), consume half the power (55 mW/channel) and deliver twice the reach (20 meters over 24-AWG cable) of current industry solutions.
30mA Low Noise LDO Regulator From Torex
Available in the ultra-small USP-4 package (1.2mm x 1.6mm x 0.6mm), as well as in standard SOT-25 and SSOT-24 (SC-82) versions, the XC6225 Series of voltage regulators from Torex Semiconductor offer exceptionally low dropout voltage – typically 70mV with 30mA load. These high current, ultra-low dropout voltage regulators provide a highly stable, low noise supply that meets the demands of battery-driven circuits such as those found in mobile and...
