HYBRID-HIGH RELIABILITY

DC/DC CONVERTER

PD - 94448E

AFL12003R3S

120V Input, 3.3V Output

Description

The AFL Series of DC/DC converters feature high power

density with no derating over the full military temperature

range. This series is offered as part of a complete family of

converters providing single and dual output voltages and

operating from nominal +28V or +270V inputs with output

power ranging from 66W to 120W. For applications requiring

higher output power, multiple converters can be operated in

parallel. The internal current sharing circuits assure equal

current distribution among the paralleled converters. This

series incorporates International Rectifier’s proprietary

magnetic pulse feedback technology providing optimum

dynamic line and load regulation response. This feedback

system samples the output voltage at the pulse width

modulator fixed clock frequency, nominally 550KHz. Multiple

converters can be synchronized to a system clock in the

500KHz to 700KHz range or to the synchronization output of

one converter. Under voltage lockout, primary and secondary

referenced inhibit, soft start and load fault protection are

provided on all models.

These converters are hermetically packaged in two

enclosure variations, utilizing copper core pins to minimize

resistive DC losses. Three lead styles are available, each

fabricated with International Rectifier’s rugged ceramic lead-

to-package seal assuring long term hermeticity in the most

harsh environments.

Notes to Specifications:

1. Parameters not 100% tested but are guaranteed to the limits specified in the table.

2. Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1.0% of

VOUT at 50% load.

3. Line transient transition time ≥ 100µs.

4. Turn-on delay is measured with an input voltage rise time of between 100V and 500V per millisecond.

5. Current limit point is that condition of excess load causing output voltage to drop to 90% of nominal.

6. Parameter verified as part of another test.

7. All electrical tests are performed with the remote sense leads connected to the output leads at the load.

8. Load transient transition time ≥ 10µs.

9. Enable inputs internally pulled high. Nominal open circuit voltage ≈ 4.0VDC.
