Choke circuits have low dc resistance Product News 8/21/2003 Post a comment Two lead-free surface-mount, common-mode choke circuits from Vishay Intertechnology Inc. are said to feature lower dc resistance (DCR), higher current-handling capability and greater stability than multilayer common-mode choke circuits, thanks to a wirewound design.
Inductor line offers EMI protection Product News 8/21/2003 Post a comment A series of surface-mount, bobbin-style inductors from C&D Technologies Inc. offers designers enhanced design flexibility with integral electromagnetic-interference (EMI) protection.
Two-phase scheme used for dc/dc Product News 8/21/2003 Post a comment Using a new two-phase spread-spectrum switching architecture to minimize harmonics, Linear Technology's LTC3252 inductorless step-down dc/dc converter can deliver up to 250 milliamps of continuous current at each output.
Single-chip MCU does energy-metering duty Product News 8/21/2003 Post a comment A line of microcontrollers from Texas Instruments Inc. combines TI's MSP430 flash MCU core and an analog front end for manufacturers developing electronic energy meters with sophisticated features such as automated meter reading, smart-card prepayment and multiple-rate billing.
Chips charge up for lithium-ion Product News 8/21/2003 Post a comment A variety of linear and switch-mode chips continues to emerge in the IC battery charger market, triggered by shrinking real estate requirements and the need for improved thermal management in charging lithium-ions, today's battery of choice.
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
