Power ICs suit USB Type-C chargers

Power Integrations says this breakthrough innovation 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, cell phones, and more.

The ICS incorporate primary switch and controller, isolated feedback, secondary control, and USB-PD controller functions into a single compact package.

Using Power Integrations patented PowiGaN technology, the ICs’ real-time telemetry power supply status and fault monitoring, combined with Power Integrations FluxLink high speed communications feedback link, produces fast, accurate secondary side regulation.

Low heat dissipation eliminates the need for bulky heat sinks and reducing component counts.

The ICs are also fully protected with input voltage monitoring, accurate brown-in/brown-out protection, and independently configurable output over- and undervoltage fault detection.

The InnoSwitch3-PD ICs are supported by the Power Integrations RDK-838 Reference Design Kit, also available from Mouser Electronics.

It features a 60 W USB PD 3.0 power supply with 3.3 V to 21 V PPS output using the onboard InnoSwitch3-PD IC.
