History of proven performance
Interpoint, a Crane Co. Company, was issued its first standard
microcircuit drawing (SMD) for a Class H hybrid in 1992. Our first
Class K hybrid SMD was issued in 1997 and we were one of the
first companies to certify manufacturing to Class K. Our Redmond
site has a DSCC approved Radiation Hardness Assurance (RHA)
plan. Our products are on DSCC SMDs with RHA “P”, “R,” or “F”
code for 30, 100 and 300 kRad(Si), respectively.
Description
The MFP Series™ of DC/DC converters do not require any
external components to achieve all specified performance
levels. They are a high-reliability, high-efficiency point of load
converter for use with a 3.3 VDC input bus or a 5 VDC input
bus. The MFP0507S model has the flexibility to be set for
any output voltage from 0.64 VDC to 3.5 VDC. The converter
operates from an input of 3.0 to 6.0 V_IN with an undervoltage
shutdown at 2.75 V, an overvoltage shutdown of 8.5 V and up
to a 15 V transient for up to 1 second.
The non-isolated, feature-rich MFP uses a Buck converter
design with synchronous rectification. The design allows the
unit to operate synchronously to no output load, ensuring
high efficiency at the lightest loads without switching off the
synchronous devices. Important features include a solid state
switch, inrush current limiting, synchronization with an external
system clock and the ability to current share allowing multiple
devices to supply a common load.
The MFP includes an internal house keeping supply that is
active at inputs as low as 2 VDC and provides a boosted and
regulated voltage supply for internal use. This internal supply
is one of the reasons that this product can provide full power
at very high efficiency at input voltages as low as 3 VDC. No
external power source or external bias is required.
The MFP converters are designed for the large, fast transient
load currents typical to digital loads. See Figure 4 for a
typical connection diagram. The MFP Series is intended to be
powered by a fully regulated power source.
