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.
