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
SAN JOSE, Calif.--(BUSINESS WIRE)--
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.
