Linear Technology has announced the LTC3452, a synchronous buck-boost DC/DC converter optimized for driving two banks of white LEDs from a single Li-Ion battery. Up to five parallel LEDs can be driven at up to 25mA each for backlighting LCD panels, while two LEDS can be driven at up to 200mA each (or one LED at 400mA) for camera flash applications. The LTC3452's synchronous buck-boost topology delivers up to 90% efficiency over the entire usable ...

The new A6281 from Allegro MicroSystems Europe is a three-channel constant-current LED driver IC with an on-chip oscillator for simple programmable brightness control. The new device is ideally suited to driving clusters of red/green/blue (RGB) LEDs in applications where the cluster forms one pixel in a large display or a lighting fixture. It precisely controls LED brightness via 10-bit pulse-width modulation (PWM) on each channel, complemented...

The A6210 from Allegro MicroSystems Europe is an LED driver IC based on a buck (stepdown) regulator circuit using constant ‘on’ time with valley current-mode control. This control scheme allows the use of very short switch ‘on’ times, making the new device ideal for applications requiring high switching frequencies combined with high input voltages and low output voltages.

Code Mercenaries launches a new product line for LED lighting applications. This is a new strategic branch of operations for Code Mercenaries. In the last few years LEDs have become a viable alternative for general lighting applications. Compared to traditional light sources LEDs offer a much longer life cycle and in most cases a significantly better energy efficiency. But the technical hurdles in designing LED based luminaires are higher than wi...
