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.

InnoMux, a new flyback control technology with multiple independently regulated outputs is eliminating DC-DC converters in certain applications.

This archive contains a code library and application programming interface (API) for controlling the InnoSwitch3-Pro IC using an Arduino microcontroller. It includes C++ and header files to support the API, code examples showing its use, and documentation on the available functionality.

In July 2019, Power Integrations announced new members of its InnoSwitch™3 families of offline CV/CC flyback switcher ICs. The new ICs feature up to 95% efficiency across the full load range and up to 100 W in enclosed adapter implementations without requiring a heatsink.

Edward Ong, product marketing manager at Power Integrations, explains how to reduce idle losses while meeting the latest safety requirements in IEC 62368-1 using Power Integrations’ CAPZero-2 IC.
