description  
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, but without the cost  
and complexity.  
The Interpoint™ MFL Series™ 28-volt dc-dc converters are rated  
up to 65 watts. On dual output models up to 70% of the rated  
output power can be drawn from either the positive or negative  
output. These hermetically sealed converters are offered with  
standard screening, “ES” screening, or fully compliant to “883”  
MIL-PRF-38534 Class H screening. See “Table 9: Element  
Evaluation” on page 13 and “Table 10: Environmental  
Screening” on page 14. Standard microcircuit drawings (SMD)  
are available. See “Table 3: SMD Number Cross Reference” on  
page 5.  
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  
feedback circuit. The output on single MFL models can be  
trimmed (see Figure 1 on page 2 for voltage changes with  
different resistor values).  
Design Features  
inhibit  
The MFL 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 MFL 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. See Table 5 on page 6 for inhibit specifications.  
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 MFL 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.  
sync  
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.
