First three-channel interleaved CCM PFC controller
Enabling high power PFC control using the smallest possible inductors, the FAN9673 has been introduced by Fairchild Semiconductor. The world's first three-channel interleaved continuous conduction mode (CCM) PFC controller (according to the manufacturer), it allows the use of the lowest possible power rating switching devices, extending the capacitors' lifetime.
Rochester re-introduces CA3080 micropower op amp
Authorised by Harris/Intersil to continue manufacturing the CA3080 and CA3080A operational transconductance amplifier (OTA), Rochester’s Extension-of-Life program provides a continuous supply of the 2MHz amplifiers. The CA3080 and CA3080A amplifiers are Gatable-Gain Blocks that utilise the unique OTA concept.
Converters boast highest power ratings in SIP format
Encapsulated in an SIP 8-pin package measuring just 21.85 x 11.1 x 9.2 mm, the ITX series of 6 Watt DC/DC converters are believed to be one of the highest power ratings available in a SIP format. The devices, from XP Power, deliver a power density of up to 46W per cubic inch with the company claiming that the series occupies much less board space than competing devices.
