Flyback Switcher ICs with built-in USB PD controller

Power Integrations has introduced the InnoSwitch3-PD family of ICs, a highly integrated solution for USB Type-C, USB Power Delivery (PD), and USB Programmable Power Supply (PPS) adapters.

A compact InSOP-24D-packaged IC, it includes a USB-C and PD controller, a high-voltage PowiGaN switch, a multi-mode quasi-resonant flyback controller, secondary-side sensing, FluxLink isolated digital feedback and a synchronous-rectification driver.

Featuring no-load power consumption as low as 14 mW, power supply designs using InnoSwitch3-PD ICs will meet all global energy-efficiency regulations.

The high efficiency of these devices also ensures low heat dissipation, eliminating the need for bulky heatsinks.

Power Integrations’ FluxLink high-speed communications feedback link ensures fast, accurate secondary-side regulation. These devices are also fully protected, with input voltage monitoring, accurate brown-in/brown-out and overvoltage protection, and output over- and under-voltage fault detection with independently configurable fault responses.
