Operational amplifier integrates cooling devices Product News 1/6/2006 Post a comment Power Amp Design's operational amplifier boasts rail-to-rail operation at both the inputs and the output combined with a power supply voltage range from ±8 volts to ±50 V (100 volt total supply voltage), and an output range up to 15 amps.
Controller combines digital manager and battery charger Product News 1/6/2006 Post a comment Summit Microelectronics' SMB118, part of a second generation of multi-output programmable power manager ICs, integrates six precision programmable regulators and a programmable battery charger to cut system size and cost in portable consumer electronics.
LED driver shows true colors Product News 1/3/2006 Post a comment Linear Technology's LTC3783, a PWM LED driver that boasts a 3000:1 dimming range for high-power LED strings and clusters, uses digitally-based True Color circuitry to eliminate the color shift normally associated with traditional LED current dimming.
PWM controller offers extra flexibility Product News 1/3/2006 Post a comment Touting a high degree of design flexibility, Intersil's ISL6420A PWM controller offers programmable switching frequency, programmable soft start, external compensation, a wide DC input (4-28 volts) to support a broad variety of applications, and two package choices.
How to dynamically mitigate power supply noise Design How-To 1/2/2006 Post a comment Learn about active noise regulation and active VLSI packaging that take advantage of proximity to the load component to place stable charge reservoirs where they are most needed, close to the high current density and high-speed, transient loads.
Backlight design for large LCD TV screens Design How-To 1/2/2006 Post a comment Today’s backlight inverters must drive CCFL backlight systems with high efficiency, low interference, reliable start up, reliable protection, and tight control of lamp current distribution under multi-lamp environments. A Microsemi engineer explains how.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
January 2016 Cartoon Caption ContestBob's punishment for missing his deadline was to be tied to his chair tantalizingly close to a disconnected cable, with one hand superglued to his desk and another to his chin, while the pages from his wall calendar were slowly torn away.122 comments
