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 […]
Super-low-voltage supervisors feature ±0.5% reset threshold accuracy for ASIC, FPGA, DSP, MCU, MPU architectures
Analog Devices announces the Power by Linear LTC2962-LTC2964 family of highly accurate 4-channel voltage supervisors for increased system voltage margin and enhanced reliability. ASIC, FPGA, DSP, MCU and MPU architectures that operate from supplies as low as 1V cannot utilize traditional 1%-2% accurate voltage supervisors without shedding valuable system voltage margin and shrinking the remaining load […]
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 […]
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 […]
