description

When used with Interpoint’s STF28-461 filter, the combination will

meet the requirements of MIL-STD-461C, CE03.

With a miniature footprint of just 0.8 square inches, the SLH

Series™ of 28 V DC/DC converters delivers 1.5 watts of output

power while saving significant board area. The wide input voltage

range of 16 to 40 VDC accepts the varying voltages of space,

military, or aerospace bus power and tightly regulates output volt-

ages to protect downstream components. Single output models

feature outputs of 5, 12, or 15 volts, and dual output models

feature outputs of ±5, ±12 and ±15 volts.

in h i b i t Fu n c t i o n

The SLH Series incorporates an inhibit terminal that can be used

to disable internal switching. The converter is inhibited when an

active low (≤ 0.5 V) signal is applied to the inhibit pin (pin 7). In

the inhibit mode the inhibit pin sources up to 2 mA maximum.

The converter resumes normal operation when an open circuit is

applied to the inhibit pin. The open circuit voltage of the inhibit is

7 to 8 volts. Do not apply an external pull-up to the converter.

Sc r e e n i n g

SLH converters offer the following screening options: Space

Prototype (O), Class H, or Class K. Radiation tolerant to

Radiation Hardness Assurance (RHA) levels of “-” (O) or “R”,

per MIL-STD-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 “Class H and K, QML Screening” tables for

more information.

Pr o t e c t i o n Fe a t u r e S

All models include a soft-start function to prevent large current

draw and minimize overshoot. The converters provide short

circuit protection (by restricting the current) and output overload

protection.

co n v e n i e n t Pa c k a g i n g

The SLH Series converters are packaged in hermetically sealed

metal cases which provide EMI/RFI shielding.

co n v e r t e r De S i g n

SLH Series DC/DC converters incorporate a flyback topology

with a variable switching frequency. Feedback provides output

voltage regulation. Output voltage is magnetically fed back to the

input side of the PWM to regulate output voltage.

Up to 80% of the load of the dual output models may be on one

output providing that the other output carries a minimum of 20%

of the total load. The dual models can be used as a single output

voltage by connecting the load between positive and negative

outputs, leaving the common unconnected resulting in double the

output voltage. (for example, SLH2805D can be used as a 10

VDC output.)
