Dynamically Configurable Off-Line Switcher IC From Power Integrations Supports USB PD 3.0 + PPS

Dynamically Configurable Off-Line Switcher IC From Power Integrations Supports USB PD 3.0 + PPS

InnoSwitch™3-Pro integrated switcher enables digital micro-stepping of voltage and current for precise battery charge control and elimination of DC-DC post-regulators

Power Integrations (Nasdaq: POWI), the leader in high-voltage integrated circuits for energy-efficient power conversion, today announced the release of its 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 new devices permit precise, dynamically adjustable, control of voltage (10 mV step) and current (50 mA step), via a simple two-wire I2C interface. Devices may be paired with a microcontroller or take inputs from the system CPU to control and monitor the off-line power supply. Applications include virtually 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.

InnoSwitch3-Pro power-conversion ICs include a microprocessor VCC supply - eliminating the need for an external LDO to power the microcontroller; also included is an n-channel FET driver which may be used to enable or disable the main power output. Together with integrated bus voltage, current and fault-reporting telemetry and dynamically configurable protection functions such as OTP, line OV/UV, output OV/UV, and short-circuit, the BOM count for a sophisticated offline power supply is significantly reduced and design complexity is dramatically simplified.

Comments Shyam Dujari, director of product marketing for Power Integrations: “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 specialized 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.”

New InnoSwitch3-Pro ICs employ Power Integrations’ high-speed digital communications technology, FluxLink™, plus synchronous rectification, quasi-resonant switching and a precise secondary-side feedback sensing and feedback control circuit. Devices are CQC certified, UL recognized and TUV (EN60950) approved to bridge the isolation barrier; the products’ InSOP™-24D package also provides a low-profile, thermally efficient solution with extended creepage (>11.5 mm) and clearance between primary and secondary sides for high reliability, surge protection and ESD robustness.

InnoSwitch3-Pro ICs target fast-charging protocols for applications such as smartphones, notebooks, tablets, smart speakers and non-charging applications that require either a load-controlled or configurable output. Samples are available now, priced at $1.12, in 10,000-piece quantities. Technical support for InnoSwitch3-Pro ICs is available from the Power Integrations website at: www.power.com/products/innoswitch/innoswitch3-pro.
