Dual full-bridge PWM motor driver IC
The new A3969 from Allegro MicroSystems Europe is a compact dual full-bridge pulse-width modulated (PWM) motor driver integrated circuit which is ideally suited to applications in portable equipment or where board space is limited.
Dual full-bridge MOSFET driver IC with microstepping translator
The A3986 from Allegro MicroSystems Europe is a dual full-bridge gate driver IC with integrated microstepping translator circuitry. The device is suitable for driving a wide range of industrial bipolar 2-phase stepper motors in the 30 to 500 W power range. Motor power is provided by external N-channel power MOSFETs at supply voltages from 12 to 50 V.
LED driver with PWM brightness control for large display applications
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...
Triple-output stepdown switching regulator IC
The new A4490 from Allegro MicroSystems Europe is a triple-output stepdown switching regulator integrated circuit providing three high-current outputs that are adjustable from 0.8 V to 5 V with a maximum current of 2 A.
LED driver IC offers high efficiency and fast switching
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.
LNBR voltage regulator IC for satellite TV receivers - Single-channel device uses small ceramic capacitors to provide low-profile solution
The A8303 from Allegro MicroSystems Europe is a new addition to the company’s family of LNBR (low-noise block regulator) ICs for use in satellite receivers and LCD TV “combo” receivers. The new device uses small ceramic capacitors rather than electrolytic devices to provide a lower-profile solution, as well as incorporating a key output voltage setting (15.6 V) to accommodate Japan-specific design requirements.
National Semiconductor Introduces New SIMPLE SWITCHER Controllers, Industry’s First Complete MOSFET Selection Tool to Simplify Controller Designs
National Semiconductor Corp. today introduced a new family of SIMPLE SWITCHER® synchronous buck controllers and the industry’s first end-to-end MOSFET selection tool to simplify switching controller designs.
Ultra Small PLL Clock Generator from Torex
