Dynamically configurable off-line switcher IC supports USB PD 3.0 + PPS

Power Integrations has released its InnoSwitch3-Pro family of configurable off-line CV/CC and CP flyback switcher ICs. These devices are capable of producing up to 65W and realising up to 94% efficiency across line and load conditions. The new devices permit precise, dynamically adjustable, control of voltage (10mV step) and current (50mA step), through a simple two-wire I2C interface. Devices can be paired with a microcontroller or take inputs from the system CPU to monitor and control the off-line power supply. Applications include practically any rapid-charging protocol, such as USB Power Delivery (PD) 3.0 + PPS, Quick Charge 4/4+, AFC, SCP, FCP, VOOC and other consumer and industrial battery chargers, dimmable LED ballast drivers, and field-configurable industrial power supplies. Shyam Dujari, director of product marketing for Power Integrations, comments: “The AC-DC power conversion market is undergoing rapid transition with system designers needing a programmable solution that can adapt to various fast-charging protocols including the recently completed USB PD 3.0 + PPS specification.” He further added, “The ability to precisely control the output voltage and current of a power supply over a wide range is also useful for designers of specialised applications with smaller production runs, as they can easily configure a single board design for multiple product SKUs using software either at manufacture or during installation.”
