Crane Aerospace & Electronics Power Solutions
Maximum Flexible Power (MFP) Single Output Point of Load
MFP0507S, 3 to 6 VDC In, 7 Amp, DC-DC Converter
Maximum Flexible Power (MFP) in a Single 7 Amp point of load.
A Use-Anywhere Power solution for digital and non-digital systems.
Features
Description
The MFP Series™ 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 5.0 VDC input
bus with an undervoltage shutdown below 3.0 volts and an
overvoltage shutdown above 6.0 volts. The MFP0507S model
has the flexibility to be set for any output voltage from 0.64
VDC to 3.5 VDC. The converter can withstand up to a 15 V
transient for up to 1 second.
No external components required
• Operating temperature -70° to +150°C
• Up to 92% efficiency, flat down to 30% load
• Qualified up to MIL-PRF-38534 Class K
• Radiation hardness assurance (RHA) up to
level R, 100 krad(Si) TID, available on request
• Input voltage range 3.0 to 6.0 VDC
• Input transient survivability to 15 VIN for up to 1 sec.
• Inhibit and sync functions
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.
• Current monitoring
• Current sharing pin for parallel operation
• Five pin-selectable, preset voltages:
-- 0.64, 0.8, 1.6, 2.5 and 3.3
• Output voltage continuously adjustable
-- from 0.8 to 3.5 V with resistors
• Indefinite output short circuit protection
• Adjustable start-up sequencing
• Remote sense and voltage margining
• Internal solid state power switch provides many benefits
including inrush current limiting
History of proven performance
Crane Aerospace & Electronics, Power Solutions was issued
its first standard microcircuit drawing (SMD) in 1992 for an
Interpoint™ Class H hybrid. 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 Defense
Logistics Agency (DLA) approved Radiation Hardness Assurance
(RHA) plan. Our products are on DLA SMDs with RHA “P” or “R”
code for 30, and 100 krad(Si), respectively.

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.
