High-efficiency power conversion IC with higher output power

With the development of science and technology, the functions of various electronic devices increase, resulting in the increase of their power consumption, which will require more and more strict power supply ICs. Therefore, it is particularly important to intelligently control the power supply output according to the different application scenarios of the loaded equipment. This article introduces a power conversion IC with high integration, high efficiency and programmable features. If you have new projects to develop, please contact APS at any time, and we will design a charging scheme for you free.

InnoSwitch4-Pro

November 15, 2022 – Power Integrations (NASDAQ stock code: POWI), a well-known company deeply engaged in the field of high-voltage integrated circuits and high-efficient power conversion, has launched a new member of InnoSwitch4 series constant voltage/constant current offline flyback switching power supply IC after years of research and development and iteration in the switching power supply IC industry. The new member IC InnoSwitch4-Pro has programmable, compact and efficient zero-voltage characteristics. With the gallium nitride (GaN) technology developed by Power Integrations, PowiGaN’s ICInnoSwitch4-Pro, in the PI highly integrated off-line flyback switch IC, the PowiGaN switch replaces the traditional silicon transistor on the primary side, thus reducing the switching loss. Compared with silicon devices, the PowiGaN product can achieve smaller size, lighter weight, and more efficient chargers, adapters, and open power supplies. Help you easily meet the standby power requirements of Energy Star, Environmental Design Directive (EuP) and other latest energy efficiency standards.

InnoSwitch4-Pro design details

InnoSwitch series IC integrates primary, secondary and feedback circuits into a surface-mounted off-line flyback switch IC at the same time. All InnoSwitch ICs are integrated with primary power switch, primary side controller, secondary side controller for synchronous rectification and innovative FluxLink technology that can eliminate optocoupler. The original intention of the InnoSwitch4-Pro design standard is to be compatible with various protocols, improve the efficiency of power transmission, reduce the cost and difficulty of the product, and meet various use scenarios without being limited by the protocol.

The efficiency of the PowiGaN-based IC in the whole load range is up to 95%, and the output power of up to 100W can be achieved without heat sink in the closed adapter application environment. Fast charger  protocols such as USB PD can significantly shorten the charging time of mobile phones, reducing the charging market from a few hours to less than 20 minutes. At the same time, users can use a charger for mobile phones, tablets and laptops at the same time, improving the user experience while reducing environmental pollution and product manufacturing costs. Multi-port chargers with three-dimensional structure can bring better user experience than single-port chargers. High-frequency and high-efficiency GaN power devices can have higher power density. Compared with multiple single-port chargers, multi-port chargers  have different advantages in terms of size, weight and space layout. Even Apple has launched dual-port chargers this year, and only one charging head is needed to meet the needs of multiple single-port chargers when going out, which can also reduce the pressure of travel on the premise of meeting green travel. The digital interface of the InnoSwitch4-Pro power supply IC can realize very intelligent and accurate current sharing design, which is convenient for the design of high efficiency and good temperature rise performance in the application of multi-port output charger.

The new product launched by Power Integrations is to better promote the development of science and technology and stimulate more productivity of power IC. In the power market of 80w-200W, a small and efficient zero-voltage switching power IC will bring more application space to handheld devices, displays, home appliances and other markets. A power supply  IC with high conversion efficiency, low temperature rise and multi-protocol support for multiple devices powered by one device will bring users a better sense of experience.

APS focuses on designing and manufacturing of all kinds Power supply adapters including wall charger/car charger/PD charger/ wireless charger/portable charger.
