Power Integrations announced the release of a suite of offline switcher ICs incorporating 900 V primary MOSFETs. The newly released devices include ICs for high-efficiency isolated flyback power supplies and for simple non-isolated buck converters. Applications include three-phase industrial power supplies up to 480 VAC, and high-quality consumer products destined for regions with unstable mains grids, tropical regions with frequent lightning strikes or any area where high-energy ring-waves and surges are prevalent.
The new products include 900 V versions of the LinkSwitch™-TN2 ICs for simple, non-isolated buck converters plus three new members of the flagship InnoSwitch™3-EP IC family, which enable extremely high-efficiency isolated flybacks up to 35 W. All members of the 900 V product families feature internal control engines optimized for high efficiency across load, enabling designs to easily meet energy-related products (ErP) limits, and a variety of line and load protection mechanisms to further enhance system robustness and reliability (Graphic: Business Wire, more info).
