App note: White LED driver with digital and PWM brightness control

An application note from Texas Instruments, white LED driver with digital and PWM brightness control (PDF!): With a 40-V rated integrated switch FET, the TPS61160/1 is a boost converter that drives LEDs in series. The boost converter runs at 600kHz fixed switching frequency to reduce output ripple, improve conversion efficiency, and allows for the use […]

Samsung Researchers Nearly Double Lithium-ion Battery Capacity

(a) A low-magnification tunneling electron microscope (TEM) image of Gr–Si nanoparticle (NP). (b) A higher-magnification image for the same Gr–Si NP from the white box in a. (Insets) The line profiles from the two red boxes indicate that the interlayer spacing between graphene layers is ~3.4 Å, in good agreement with that of typical graphene layers

Plus 50% of power for a scant one Euro?

High efficiency, low standby power consumption and a power reserve, all this can be gained with a new adapter from our portfolio. Minwa NR120P150PGS/E+ is in fact an “ordinary“ adapter with a fixed output voltage 12VDC/1500 mA. But it´s worth to mention, that it meets everything, what we usually require from a modern mains adapter:

Rohde & Schwarz HMC8043 PSU: Review and Teardown

First Impressions Bench power supplies aren’t really pieces of kit that get your pulse racing, they just sit there doing their job, in some cases giving gentle background heating to keep the lab warm in the winter and providing enough ballast to stop your bench wobbling about too much. The traditional bench top power supply
