description

mode feedback loop improves transient response in a manner

similar to primary current mode control and allows for ease of

paralleling, but without the cost and complexity.

The Interpoint™ SMFL Series™ 28-volt DC/DC converters

are rated up to 65 watts output power over a -55° to +125°C

temperature range with a 28 VDC nominal input. On dual output

models up to 70% of the rated output power can be drawn from

either the positive or negative outputs. Current sharing allows

the units to be paralleled for total power of up to 185 watts. The

welded, hermetically sealed package is only 3.0 x 1.5 x 0.40

inches, giving the series an overall power density of up to 43

watts per cubic inch.

The constant frequency, pulse-width modulated converters use

a quasi-square wave single-ended forward design. Tight load

regulation is achieved through a wide-bandwidth magnetic feed-

back circuit. The output voltage on single SMFL models can

be trimmed to a specific output voltage by adding an external

resistor (see Figure 1 for resistor values).

Sc r e e n i n g

in h i b i t

SMFL converters, also available on SMD drawings, offer the

following screening options: Space Prototype (O), Class H, or

Class K. Radiation tolerant to Radiation Hardness Assurance

(RHA) levels of “-” (O), “P,” or “R,” per MIL-PRF-38534. Interpoint

model numbers use an “O” in the RHA designator position to

indicate the “-” (dash) Radiation Hardness Assurance level of

MIL-PRF-38534, which is defined as “no RHA”. See Screening

Tables 1 and 2

The SMFL Series converters have two inhibit terminals (INH1

and INH2) that can be used to disable power conversion,

resulting in a very low quiescent input current and no generation

of switching noise. An active low (<0.8 volts) is required to inhibit

the converter between INH1 (pin 4) and Input Common (pin

2). An active low (<0.5 volts) is required to inhibit the converter

between INH2 (pin 12) and Output Common (pin 8).

Sy n c

De S i g n Fe a t u r e S

Converters may be synced to an external clock (525 to 675 kHz)

or to one another by using the sync in or out pins. The nominal

free-run switching frequency is 600 kHz.

SMFL Series converters are switching regulators that use a

quasi-square wave, single ended forward converter design with a

constant switching frequency of 600 kHz typical.

Isolation between input and output circuits is provided with a

transformer in the forward path and a wide bandwidth magnetic

coupling in the feedback control loop. The SMFL uses a unique

dual loop feedback technique that controls output current with

an inner feedback loop and an output voltage with a cascaded

voltage mode feedback loop. The additional secondary current

Multiple SMFL converters may be used in parallel to drive a

common load (see Figure 2). Only single output models with

SENSE and SNS RTN can be used in the share mode. In this

mode of operation the load current is shared by two or three
