mode connectivity, the SDK supports Cypress’ Wi-Fi
and Bluetooth combination solutions and its Bluetooth
and Bluetooth Low Energy devices. The SDK enables
cloud connectivity in minutes with its robust libraries
that uniquely integrate popular cloud services such as
Amazon Web Services, IBM Bluemix, Alibaba Cloud,
and Microsoft Azure, along with services from private
cloud partners. WICED also supports iCloud remote
access for Wi-Fi-based accessories that support
Apple® HomeKit™, which enables hub-independent
platforms that connect directly to Siri voice control and
the Apple Home app remotely.
Cypress’ WICED Studio connectivity suite is
microcontroller (MCU)-agnostic and provides ready
support for a variety of third-party MCUs to address
the needs of complex IoT applications. The platform
also enables cost efficient solutions for simple IoT
applications by integrating MCU functionality into the
connectivity device. Wi-Fi and Bluetooth protocol stacks
can run transparently on a host MCU or in embedded
mode, allowing for flexible platform architectures with
common firmware. More information on Cypress’
WICED platform, ecosystem and community is

The CYW43012 combo solution is currently sampling
to lead customers. Full production is expected in the
fourth quarter of 2017.
Vicor Introduces New 700V K of 1/16 Bus
Converter
Vicor has added a new fixed-ratio high-voltage bus
converter to its bus converter module (BCM) lineup. The
new 700V K of 1/16 BCM offers a power level of 1.75
kW and a peak efficiency of 97%, with a power density
of 700W/in³. The device is available in the thermally
adept 4414 (111mm x 36mm x 9.3mm) VIA package,
with either a chassis-mount or board-mount option and
4.3 kV of galvanic isolation. The robust VIA package
also provides integrated PMBus™ communication,
EMI filtering, and voltage transient protection. These
flexible modules can be easily paralleled into higher
power arrays. In addition, the BCM outputs can be
connected in series for higher output voltages.
BCMs are ideal power components for a broad range
of applications such as tethered unmanned vehicles,
power distribution systems, and 3-Phase front ends.
BCM’s can also be used as isolated unregulated front
ends, which can then feed a multiplicity of Vicor’s ZVS
PoL Buck and Buck-Boost regulators or PRMs and
VTMs in a factorized power architecture.
The new higher voltage BCMs are available in either
“T-Grade” (-40˚C to 100˚C) or “C-Grade” (-20˚C to 100˚C)
temperature grades. A Mil-Grade rating (-55˚C to 100˚C)
is scheduled for release by the end of 2017.
Providing DC-DC conversion after AC rectification and
PFC, the 700V BCM provides a small, efficient, power
component for power system designers to develop very
compact and cost-effective 3-Phase systems with an SELV
output. The 400V – 700V input capable device addresses
nominal 380VRMS and 400VRMS input AC-DC conversion
needs, commonly found in industrial applications.
Remote Unmanned Vehicles Benefit from High-
Voltage DC Transmission and Bidirectional
Capability
The 1:16 transformation ratio and
bidirectional operation makes the UHV BCM an
ideal solution for remote unmanned vehicles used
in air, sea, or underground exploration. Bidirectional
operation enables systems to step up then step
down line voltage to take advantage of reduced I2R
losses, which dramatically improves power distribution
cable size, weight, and costs with significant system
efficiency improvements. By using higher voltages for
transmission, the tether cross sectional area and thus
the weight can be reduced to allow for greater operating
range of the UAV.
