During PCIM Europe 2025 in Nuremberg, Mark Gerald Manango gave a poster presentation showcasing a 140 W USB PD 3.1 notebook adapter that achieves high efficiency across the load range. Our InnoSwitch5-Pro digitally controllable switcher ICs achieve Zero-Voltage Switching without a dedicated and costly additional high-voltage switch.

The HiperPFS-5 family of integrated PFC ICs features a 750-V PowiGaN switch for high efficiency across the load range. It offers an elegant solution to keep the power factor high during low load. PI Director of Technical Outreach Andy Smith explains how it works in this new article.

EE Times turned 50 last year and has reported on innovation in all electronics fields throughout its history. In the world of analog and power electronics, Power Integrations has been a key innovator since its inception in 1988. Power Electronics News spoke with CEO Balu Balakrishnan about his experience and vision.

HiperPFS-5 ICs are the first use of PowiGaN power switches in Power Factor Correction (PFC) to minimize conduction losses, delivering greater than 98% efficiency at 240 W. This new article by PI Director of Technical Outreach Andy Smith explains the variable-frequency discontinuous-conduction–mode (DCM) techniques used in the HiperPFS-5 devices to

Everyone likes smaller AC-DC adapters, and GaN technology has hastened the production of high-density converters. Despite this progress, the bulk capacitor remains challenging to shrink. Power Integrations has a solution with its MinE-CAP ICs, which dynamically adjust bulk input capacitance based on input voltage. This results in a substantial reduction of occupied volume, making it easier for designers to meet high power density requirements.

The pressure on the designer is relentless - develop ever-smaller chargers and adapters that deliver full USB-C Power Delivery (PD), Programmable Power Supply (PPS) functionality, and faster charging times for smartphones, tablets, notebooks and other portable devices. Keys to designing smaller chargers and adapters include reducing component count and maximizing

This article briefly reviews the need for a primary clamp circuit in flyback power supplies. It then compares and contrasts the use of passive clamping with complementary and non-complementary active clamping solutions and introduces a chipset that enables the use of non-complementary clamping solutions and the design of super-dense flyback

This article briefly reviews the physics behind magnetizing interference in flyback power supplies and presents an anti-magnetizing interference dual-output isolated flyback power supply design. It closes with a discussion of testing and a performance comparison between an anti-magnetizing interference power supply and a conventional design.

Power Integrationsの製品マーケティングマネージャーであるEdward Ongは、CAPZero-2集積回路を使用して、IEC 62368-1の最新の安全要件を満たしながらアイドル損失を削減する方法を説明しています。

During PCIM Europe 2025 in Nuremberg, Trung Huynh gave a poster presentation about optimizing efficiency across input line and load. Our new TinySwitch-5 flyback switcher ICs feature an advanced control engine which seamlessly manages switching frequency and power delivery to maximize efficiency, even at light loads.

PI power devices integrate a high-voltage switch and provide internal isolation. This enables the design of compact power supplies that meet safety requirements of demanding applications like EVs.

During PCIM Europe 2025 in Nuremberg, Adrian Umadhay gave a poster presentation about modeling frequency response to maximize performance.

During PCIM Europe 2025 in Nuremberg, Thomas Anthony Capobianco gave a poster presentation introducing a multi-output flyback design for meters that can protect against magnetic interference. With a low-RDS (ON), 900 V MOSFET, our LinkSwitch-XT2 switcher ICs improves efficiency at full-load, maintains efficiency at light-load and resists magnetic tampering.

During PCIM Europe 2025 in Nuremberg, Han Cui gave a poster presentation about replacing SiC switches with 1700 V GaN devices in high-input voltage industrial applications. The world's first 1700 V GaN switch is now available in a new member of the InnoMux-2 flyback switcher IC family. In less than two years, Power Integrations has delivered three voltage-rating breakthroughs with its #PowiGaN technology, from 900 V to 1250 V, and now 1700 V.

The InnoMux-2 switcher IC family is a revolutionary single-stage flyback solution for multi-output power supplies. It improves efficiency and accurately regulates all outputs.

PI's industry-first 1250 V GaN-based switcher ICs allow significant transient overvoltage capability, which is crucial to EV and industrial applications that require high voltage and high reliability.

2019 年 7 月、Power Integrations はオフライン CV/CC フライバック スイッチング電源用 IC の InnoSwitch™3 ファミリーの新製品を発表しました。この新しい IC では、全負荷範囲で最大 95% の効率、そして密閉型アダプタの実装において最大 100 W をヒートシンクなしで実現します。
