GaN-powered LED drivers target compact smart-lighting designs
Power Integrations announced a new member of the LYTSwitch-6 family of safety-isolated LED drivers for smart lighting applications – the LYT6078C. This new LYTSwitch-6 IC uses Power Integrations’ PowiGaN™ gallium nitride (GaN) technology to deliver efficiency and performance benefits, demonstrated by the new design example report (DER-920) the company is also announcing today. The PowiGaN-based LYT6078C […]
Configurable mixed-signal IC includes four high-drive outputs for 12-V motor apps
The SLG47105 motor drive CMIC delivers the benefits of both configurable logic and configurable analog with high-voltage outputs, all encapsulated within a tiny 2×3-mm QFN package. The SLG47105 joins Dialog’s widely adopted GreenPAK product family and provides a more cost-effective, one-time NVM programmable option for designers looking to integrate both digital and analog system functions […]
Low-current LED driver ICs optimized for LED strips, architectural and appliance lighting
Infineon Technologies AG released the BCR431U, a constant current linear LED driver IC that provides low-voltage drop performance for regulating LED current. It is the second device released in the new generation BCR family with low voltage drop focusing on low current designs of up to 37 mA. Typical applications for the new BCR431U include […]
Ultra-compact high output linear LED driver ICs optimized for automotive apps
Rohm announced the development of an ultra-compact high output linear LED driver IC (BD18336NUF-M) that provides stable lighting even in the event of battery voltage drops on a single chip, making it ideal for a broad range of socket-type LED lamps used in vehicle systems, from DRLs (Daytime Running Lamps) and position lighting to rear lamps. […]
Ultra-small power MOSFET gate drivers cut parasitic inductance problems
Each time a power MOSFET is being turned on or off in a SMPS, parasitic inductances produce ground-shifts that may cause false triggering of the gate-driver IC. Infineon Technologies AG adds a device to its cost-effective and compact-size EiceDRIVER 1EDN TDI (truly differential inputs) 1-channel gate-driver family to prevent such consequences. The new device (1EDN7550U) is […]
4-channel LED driver ICs with built-in MOSFETs target automotive uses
Rohm recently announced the availability of 4ch linear LED driver ICs with built-in MOSFET ideal for LED rear lamps (turn/stop), fog lamps and turn signals for automotive use. In recent years the adoption of automotive-grade LED lamps is advancing from the viewpoint of power savings and design flexibility, while the number of lamps and brightness […]
SiC MOSFET driver with fast short-circuit response achieve AEC-Q100 qualifications
Power Integrations today announced that its SIC118xKQ SCALE-iDriver, a high-efficiency, single-channel gate driver for silicon carbide (SiC) MOSFETs, is now certified to AEC-Q100 for automotive use. Devices can be configured to support gate-drive voltage requirements of commonly used SiC MOSFETs and feature sophisticated safety and protection features. The SIC1182KQ (1200 V) and SIC1181KQ (750 V) SCALE-iDriver […]
Gate drivers handle 4.5 kV press-pack IGBT modules
Power Integrations introduced the 1SP0351 SCALE-2 single-channel, +15/-10 V, plug-and-play gate-driver, developed specifically for new 4500 V press-pack IGBT (PPI) modules from manufacturers such as Toshiba, Westcode and ABB. Based on Power Integrations’ widely used SCALE-2 chipset, the new gate-drivers are perfectly suited for high-reliability applications such as HVDC VSC, STATCOM/FACTS and medium-voltage drives. The […]
Variable-speed motor drive controller includes ARM Cortex-MO core
Infineon Technologies AG is releasing the new IMC300 motor controller series. It combines the iMOTION Motion Control Engine (MCE) with an additional microcontroller based on the Arm Cortex-M0 core. IMC300 complements the IMC100 series and aims at variable speed drives that require very high application flexibility. Both families, IMC100 and IMC300, share the same implementation […]
