Designing the fast-charging, small adapters consumers are expecting today poses a not unfamiliar challenge to the designers of those devices. How do you deliver loads of power safely and efficiently when the increased component count and complexity of providing sophisticated charging control means a larger adapter? Even a more efficient circuit design requires new ways […]

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 […]
APEC a no-show but Power Integrations is not — virtually
Yes, APEC 2020 organizers are promising paper presentations online but it looks like one fast and furious Silicon-Valley-based supplier of power electronics just took up the virtual-exhibit show banner with today’s launch of the Power Integrations Virtual Booth — APEC 2020. The premier global event in applied power electronics that was to take place this […]
GaN flyback switcher ICs enable 55-W heatsinkless power supplies
Power Integrations announced an expansion of its InnoSwitch 3 families of offline CV/CC flyback switcher ICs. The new INN3x78C devices incorporate a smaller “size 8” 750 V PowiGaN transistor, enabling compact, efficient power supplies delivering between 27 W and 55 W without heatsinks. The ICs are housed in the same high-creepage, safety-compliant InSOP™-24D package as larger […]
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 […]
