Power Integrations’ InnoSwitch3-Pro integrated switcher supports USB PD 3.0 + PPS

March 20, 2018 Rich Nass

Some in our industry would say that the power sector moves painfully slow. If you were at APEC last week, you’d know that such a statement is a foolish one. Further evidence comes from Power Integrations, who released the InnoSwitch3-Pro family of configurable off-line CV/CC and CP flyback switcher ICs.

Capable of delivering up to 65 W and achieving up to 94% efficiency across line and load conditions, the devices permit precise, dynamically adjustable, control of voltage (10 mV step) and current (50 mA step), via a simple two-wire I2C interface. Devices can be paired with an MCU or take inputs from the system CPU to control and monitor the off-line power supply.

Applications include any rapid-charging protocol, including USB Power Delivery (PD) 3.0 + PPS, Quick Charge 4/4+, AFC, VOOC, SCP, FCP and other industrial and consumer battery chargers, dimmable LED ballast drivers and field-configurable industrial power supplies.

The InnoSwitch3-Pro power-conversion ICs include a microprocessor VCC supply, which eliminates the need for an external LDO to power the MCU; also included is an n-channel FET driver that can enable or disable the main power output. Samples are available now, priced at $1.12, in 10,000-piece quantities.
