Power Integrations InnoSwitch3-PD ICs

The InnoSwitch3-PD family of ICs, from Power Integrations, provides engineers with a highly integrated solution for USB Type-C, USB Power Delivery (PD) and USB Programmable Power Supply (PPS) adapters for laptops, tablets, mobile phones and more.

The IC incorporates primary switch and controller, isolated feedback, secondary control and USB-PD controller functions into a single, compact package. Using PowiGaN technology, the IC’s real-time telemetry power supply status and fault monitoring, combined with FluxLink high-speed communications feedback link, produces fast secondary side regulation.

The ICs are designed to offer low heat dissipation, eliminating the need for bulky heat sinks and reducing component counts. They are also fully protected with input voltage monitoring, brown-in/brown-out protection and independently configurable output over- and undervoltage fault detection.
