Step-down regulator integrated to low-noise, LDOs for ultra-quiet operation
Analog Devices, Inc. (ADI) introduced a super low noise dual output DC/DC μModule regulator with patented silicon, layout, and packaging innovations. Operating from up to 40 V input, the LTM8080’s front-end is a high-efficiency synchronous Silent Switcher step-down regulator followed by two separate low noise, low dropout (LDO) regulators. To further suppress switching noise, the […]
Efficient triple 3.6 kW LLC set designed for on-board chargers
On-board chargers are typically integrated into the vehicle’s powertrain and require transformers to convert the AC power from external charging stations or home charging units, into the DC power needed to charge the vehicle’s battery. Premo has developed an efficient triple 3.6 KW LLC (suited for 400V Input) set with a transformer and resonance inductor […]
100 kHz reference inverter is 98.5% efficient at 5% load
Pre-Switch, Inc. has announced new data proving the efficiency of the company’s architecture at low load as well as a full load. Tests performed on Pre-Switch’s CleanWave2 reference inverter at 100kHz switching speed show the system is 98.5% efficient at 5% load. Peak efficiency is 99.57%. Pre-Switch eliminates switching losses, enabling 10X higher switching frequencies, […]
Circuit boards don’t behave the way you think they do
Circuit designers increasingly must concentrate on the design of transmission lines, or the “spaces” between traces, instead of the “wires” on a circuit board. By Daniel Beeker, Technical Director, Automotive Field Applications Engineering, Senior Member, IEEE, NXP Semiconductors When it comes to the design of printed circuit boards, the industry focus has been on the […]
