Power Integrations adds INN3x78C to InnoSwitch3 IC range
Power Integrations has expanded its InnoSwitch3 family of offline CV/CC flyback switcher ICs, with the INN3x78C.
It incorporates a smaller, “size 8” 750V PowiGaN transistor, enabling designers to product compact, efficient power supplies delivering between 27 and 55W without heatsinks. The ICs are housed in the same high-creepage, safety-compliant InSOP-24D package as larger members of the GaN-based InnoSwitch3 families, which target up to 120W.
PowiGaN technology delivers up to 94 per cent efficiency across line and load, making it resistant against line surges and swells commonly seen in regions with unstable mains voltage, says Power Integrations. Their use enables OEMs to specify a single power supply design to be used worldwide in applications as diverse as USB PD and high-current chargers/adapters for mobile devices, as well as set-top boxes, displays, networking and gaming products and appliances, especially those aiming to comply with the planned European Energy Labeling Regulation.
Comments Chris Lee, director of product marketing at Power Integrations, said: “Simultaneous electrical strength and efficiency are difficult to achieve due to the relationship between silicon MOSFET breakdown voltage and COSS-related switching loss. Our electrically strong PowiGaN transistors have very low COSS . . . and low field return rate from tropical markets”.
The InnoSwitch3 ICs are available now with InnoSwitch3-CP and InnoSwitch3-EP.
Power Integrations specialises in semiconductor technologies for high-voltage power conversion. The company’s products are used in the clean-power ecosystem, enabling the generation of renewable energy as well as the efficient transmission and consumption of power in applications ranging from mW to MW.
