DESCRIPTION  
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, mili-  
tary, or aerospace bus power and tightly regulates output voltages  
to protect downstream components. Single output models feature  
outputs of 3.3, 5, 12, or 15 volts, and dual output models feature  
outputs of ±5, ±12 and ±15 volts.  
connecting the load between positive and negative outputs, leaving  
the common unconnected resulting in double the output voltage.  
(ex: SLH2805D can be used as a 10 VDC output.)  
When used with Interpoint’s STF filter, the combination will meet the  
requirements of MIL-STD-461C, CE03.  
INHIBIT FUNCTION  
When an open collector TTL logic low is applied to the inhibit  
terminal, pin 7, the converter shuts down and lowers the output  
voltage to near zero and input current to as low 5 mA. Leaving the  
terminal open or applying an open collector TTL logic high will  
enable the converter.  
SCREENING AND REPORTS  
SLH converters offer three screening options – Standard, Class H,  
or Class K – and three levels of radiation hardness. See Section C2,  
Quality Assurance, pages C2-7 through C2-9, for descriptions.  
Detailed reports on product performance are also available and are  
listed on page C2-9.  
PROTECTION FEATURES  
All models include a soft-start function to prevent large current draw  
and minimize overshoot. The converters provide short circuit protec-  
tion (by restricting the current) and output overload protection.  
CONVERTER DESIGN  
SLH Series DC/DC converters incorporate a flyback topology with a  
variable frequency of approximately 370 kHz. Feedback provides  
output voltage regulation. Output voltage is magnetically fed back to  
the input side of the PWM to regulate output voltage. Regulation is  
also affected by the load.  
CONVENIENT PACKAGING  
The SLH Series converters are packaged in hermetically sealed  
metal cases which provide EMI/RFI shielding.  
For more information, contact your Interpoint representative  
listed in Section A5.  
Dual models regulate the negative output with magnetic coupling to  
the positive output. Up to 80% of the load 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
