Power Integrations Unveils Complete Range of Switcher ICs with Integrated 900 V MOSFETs
Power Integrations announced the release of a suite of offlineswitcher ICs incorporating 900 V primary MOSFETs. The newly releaseddevices include ICs for high-efficiency isolated flyback power suppliesand 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.

The 900 V LinkSwitch-TN2 ICs deliver the lowest-component-count switcher solutions for buck converters. Devices feature selectable current limit and fully integrated auto-restart for short-circuit and open-loop protection. The use of frequency jittering greatly reduces EMI, and devices easily meet high-voltage creepage and clearance requirements between DRAIN and all other pins both on the PCB and at the package.

The 900 V InnoSwitch3-EP flyback switcher ICs provide lossless line OVP sensing, which automatically interrupts switching when line voltages exceed a selected threshold, preventing damage to the power supply during severe line overvoltage situations. Devices achieve industry-leading efficiencies of up to 90% across line and load conditions, reducing power supply losses and resulting in compact power supplies up to 35 W without heatsinks. The 900 V InnoSwitch3-EP ICs employ Power Integrations’ innovative isolated digital communications technology, FluxLink™, plus synchronous rectification (SR), QR switching and a precise secondary-side feedback sensing and control circuit. This results in highly efficient, accurate, reliable power supply circuits without the need for unreliable optocouplers.

Comments senior product marketing manager Silvestro Fimiani: “These switching power ICs enable designers of three-phase utility meters, motors, industrial auxiliary power supplies, appliances and even cellphone chargers to realize a truly ‘one-world’ power supply that meets the reliability expectations of users everywhere. For example, OEMs addressing the burgeoning market in India for high-quality consumer products suffer a continuous stream of electrically damaged and returned products that must be serviced or replaced. Our 900 V switcher ICs provide effective and inexpensive protection and a substantial reduction in operating and product-support costs.”

Samples of the 900 V InnoSwitch3-EP ICs are available now, priced at $1.18 for 10,000-piece quantities. Samples of 900 V LinkSwitch-TN2 ICs are also available priced at $0.60 for 10,000-pieces orders. Technical support for the 900 V family of ICs is available from the Power Integrations website at: https://ac-dc.power.com/applications/unstable-mains-voltage.
