description

The Interpoint

SMFLHP Series™ 28 volt dc-dc converters are

rated up to 100 watts output power over a -55°C to +125°C

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

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

either the positive or negative outputs. The welded, hermetically

sealed package is only 3.005 x 1.505 x 0.400 inches.

SMFLHP converters offer screening options to 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) RHA level of

MIL-PRF-38534, which is defined as “no RHA”. See “Table 9:

Element Evaluation” on page 14 and “Table 10: Environmental

Screening and RHA Levels” on page 15 for more information.

Isolation between input and output circuits is provided with a

transformer in the forward path and wide bandwidth magnetic

coupling in the feedback control loop. The SMFLHP Series

uses a unique dual loop feedback technique that controls output

current with an inner feedback loop and output voltage with a

cascaded voltage mode feedback loop.

The additional secondary current mode feedback loop improves

transient response in a manner similar to primary current mode

control and allows for ease of paralleling.

Tight load regulation is achieved through a wide-bandwidth

magnetic feedback circuit.

The SMFLHP Series converters are switching regulators that use

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

a constant switching frequency of 600 kHz.

The SMFLHP 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. See Table 5 on

page 6 for specifications.

ync

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

or to one another by using the sync in or out pins. See Table 5 on

page 6 for specifications.
