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.
