Flyback Switcher ICs with On-Chip USB PD Controller

 

Power Integrations announced on September 21 the InnoSwitch™3-PD family of ICs, a highly integrated solution for USB Type-C, USB Power Delivery (PD), and USB Programmable Power Supply (PPS) adapters. This compact InSOP™-24D-packaged IC 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 meet all global energy-efficiency regulations. The high efficiency of these devices ensures low heat dissipation, eliminating the need for bulky heatsinks. Power Integrations’ FluxLink high-speed communications feedback link ensures fast, accurate secondary-side regulation. InnoSwitch3-PD ICs 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. “InnoSwitch3-PD ICs designers seeking the ultimate in charger power density. This requires the highest level of integration and maximum efficiency to limit self-heating. Our latest addition to the InnoSwitch3 family simplifies the development and manufacturing of compact, energy-efficient USB PD3.0 power supplies for smartphones, tablets, notebooks, and other devices that benefit from fast charging. InnoSwitch3-PD ICs reduce the BOM count with sixty components only to half that of conventional designs, reducing design time and simplifying high-volume manufacture for slim, ultra-compact OEM and aftermarket chargers”, commented Aditya Kulkarni, senior product marketing engineer at Power Integrations.

The new InnoSwitch3-PD ICs are priced from $1.30 per unit in 10,000-unit quantities.
