Flyback regulator delivers 5W & operates at 150°C

Flyback regulator delivers 5W & operates at 150°C
  Linear Technology announces the H-grade version of the LT8303, a monolithic flyback regulator with guaranteed operation for junction temperatures as high as 150°C. By sampling the isolated output voltage directly from the primary-side flyback waveform, the part requires no opto-isolator or third winding for regulation.

MOSFET-based evaluation board cuts design costs

MOSFET-based evaluation board cuts design costs
A new evaluation board from Wolfspeed, a Cree Company is available at Richardson RFPD. The CRD-060DD17P-2 is a demonstration board for a single-end flyback converter design built with Wolfspeed’s commercially-available 1700V SiC MOSFET. The 48W experimental reference design demonstrates how the 1700V SiC MOSFET can reduce total cost and simplify the design of auxiliary power supply.

Chip provides secure wireless chargers

Chip provides secure wireless chargers
Counterfeit chargers for portable electronics are a major problem. At the end of 2016, Apple claimed that of 100 Apple-branded charging accessories it bought on Amazon, 90 were counterfeits. Around the same time, Britain’s Chartered Trading Standards Institute reported that of 400 counterfeit chargers it bought from a range of online retailers, 397 failed a basic safety test.

Pioneering chip extends sensors' battery life

Pioneering chip extends sensors' battery life
A low-cost chip that enables batteries in sensors to last longer, in some cases by over ten times, has been developed by engineers from the University of Bristol. Dr Bernard Stark and colleagues in the Bristol Electrical Energy Management Research Group based in the Merchant Venturers School of Engineering, have developed a voltage detector chip that requires only a few trillionths of a watt (picowatts) to activate other circuits.

Flyback regulator delivers up to 15W

Flyback regulator delivers up to 15W
  Linear Technology announces the LT8315, a high voltage monolithic flyback regulator that simplifies the design of an isolated DC/DC converter. By sampling the reflected isolated output voltage across the third winding on the power transformer, the part requires no opto-isolator or LT1431 for regulation.
