MALVERN, Pa - Vishay Intertechnology, Inc. announced that it
is making all of its FunctionPAK® dc-to-dc converters and current control modules available in a new
surface-mount adaptor board configuration to support engineering prototype assembly.
While most production operations can handle the standard FunctionPAK surface-mount BGA
configuration, the new “SM“ (FX4040 G7XX ADJ SM, FX5545 GXXX XXX SM, FX5959 G701 ADJ SM) versions of the
FunctionPAK devices will facilitate the assembly process for any engineering lab that finds it difficult to handle
the BGA configuration in its prototype assembly lab.
The surface-mount adaptor board is modeled on the
BGA package, but the device’s contacts have been modified to extend out from under the package to scalloped
castellations around the edges of the adaptor board. Either a reflow solder connection or hand soldering can be
The “SM“ (FX4040 G7XX ADJ SM, FX5545 GXXX XXX SM, FX5959 G701 ADJ SM) versions are the
second of two FunctionPAK options expressly intended to streamline the design prototype process. Also available is a
“PI“ series of plug-in versions of all devices in the FunctionPAK® family, which can be plugged
easily into a "bread board" for prototyping and testing. The “PI“ series devices offer a 0.1-in. grid
pin configuration for soldering directly into the circuit board and a standard socket for the added flexibility of
switching different modules in and out of the circuit.
Vishay FunctionPAK dc-to-dc converters are the
smallest, lowest-profile complete dc-to-dc converter solutions in the industry, requiring no external components to
achieve the complete circuit function. Intended primarily for point-of-load converters in intermediate bus
architectures, these converters are available as either boost or buck converters with power output up to 15 W and
output current up to 4 A. Input voltages from 2.5 V to 6 V are converted to output voltages of 0.8 V to 6 V with
efficiencies up to 95%.
Vishay current control products, also available in the surface-mount adaptor
board configuration, include the 15 W, 2.5 A power LED driver and the smaller 60 W, 2 A (max.) current controller.
The controller is available with a single channel or with two channels (one or two independent controllers) in the
While intended primarily for prototyping operations, FunctionPAK “SM“
(FX4040 G7XX ADJ SM, FX5545 GXXX XXX SM, FX5959 G701 ADJ SM) versions are also available in production quantities.
Both samples and production quantities are available now, with lead times of six weeks for larger orders.
