Nonsynchronous boost controller that drives two MOSFET stages
Analog Devices announces the Power by Linear LTC7840, a 2-phase nonsynchronous boost controller that drives two stages of external N-channel power MOSFETs. It is configurable as single or dual output boost regulator or for higher voltages, the output of the first channel can feed the input of second channel allowing an output voltage which exceeds several […]
Buck-boost controller targets 12-V/12-V redundant battery systems in autonomous vehicles
The Power by Linear LT8708/-1 is a 98% efficient bidirectional buck-boost switching regulator controller that operates between two batteries that have the same voltage, as are used for redundancy in self-driving cars. The LT8708/-1 operates from an input voltage that can be above, below or equal to the output voltage, making it well suited for […]
Low-cost 2-W dc/dc converters offer high isolation
The RKZE series is a cost-effective 2-W dc/dc converter in an industry standard SIP7 case. The extended operating temperature range runs from -40° to +95°C, making these converters suitable for demanding environments in industrial, test and measurement applications as well as high-volume manufacturing. They are pin-compatible with the RK and RH converter series, offering a […]

BGA package option comes to 48-V ZVS buck regulator series
Vicor Corporation announced the PI354x-00-BGIZ, the latest addition to the 48V Cool-Power ZVS Buck Regulator portfolio, offering a new BGA package option to the existing PI354x-00-LGIZ LGA series. PI354x Cool-Power ZVS Buck Regulator’s high-performance ZVS topology enables 48V direct to PoL without sacrificing performance. With step-down regulation from a higher voltage source, engineers can deploy […]
Step-down ultrathin regulator module handles ASIC, FPGA loads
Analog Devices announces the Power by Linear LTM4686, a dual 10A or single 20A ultrathin step-down µModule regulator with a PMBus interface housed in a 16mm x 11.9mm x 1.82mm LGA package. The 1.82mm package height allows the LTM4686 to be placed on a PC board very close to its load such as an FPGA or […]
Vehicle electrical systems: Zero-to-sixty in 48 volts
Versatile automotive 48-V electrical systems will reduce CO2 emissions and make practical super-efficient electrical subsystems. Joseph Pulomena, EPCOS, a TDK Group Co. NEARLY five years ago, the U.S. government issued rules requiring automakers to hit a fleet average of 54.5 mpg for new cars and trucks – nearly doubling average fuel economy. Electric vehicles and […]
Are power systems up to the task of running self-driving cars?
Automotive electronics depends on power supplies that can handle abuse like load dumps. New ICs are optimized for these extreme environments and can meet stringent vehicle safety standards. Tony Armstrong, Analog Devices Inc. THE auto industry expects a transition to autonomous vehicles via both an evolutionary path, where existing cars get there little by little […]
Auto-qualified, high-efficiency, 3.2-MHz synchronous quad output buck regulators feature low EMI
Analog Devices announces the Power by Linear ADP5138, automotive qualified, high efficiency, 3.2MHz synchronous quad output buck regulators, incorporating a unique fixed frequency, peak current mode, PWM control architecture that reduces conducted and radiated emissions. The device’s high efficiency buck regulators improve thermal management, operate down to 0.8V outputs and deliver up to 1A of continuous output […]
