HIGH RELIABILITY
HYBRID DC-DC CONVERTERS
Description
The ASAP Series of DC-DC converters are high
reliability thick film hybrid converters that use flyback
topology operating at a nominal frequency of 550KHz.
High input to output isolation is achieved through the
use of transformers in the flyback power and feedback
circuits.
ASAP
The advanced feedback design provides fast loop
response for superior line and load transient
characteristics and offers greater reliability than devices
incorporating optical feedback circuits.
Features
n Up To 6.0 Watt Output Power
n Availabe in Single and Dual Output Configurations
Single Outputs: 5V, 12V and 15V
Dual Outputs: ± 5V, ± 12V and ± 15V
n High Reliability
This device is designed to meet MIL-STD-704D input
requirements offering full performance over a wide 15
to 50 volt input range and output power of up to 6.0 watts.
n Wide Input Voltage Range, 15 To 50 Volts
n Indefinite Short Circuit and Overload Protection
n Popular Industry Standard Pin-Out
n Military Screening Available
n Parallel Seam Welded Package
n No External Capacitors Required
n Input Voltage Surge Protected to MIL-STD-704A
80V, 1 second
Connecting the inhibit pin (pin 5) to the input common
(pin 7) will cause the converter to shut down. It is
recommended that the inhibit pin be driven by an open
collector device capable of sinking at least 400µA. The
open circuit voltage of the inhibit pin is 11.5 ±0.5 volts.
These converters are manufactured in a facility fully
qualified to MIL-PRF-38534. All processes used to
manufacture these converters have been qualified
thereby enabling International Rectifier to deliver fully
compliant devices. Four standard temperature grades
are offered with the screening options. Refer to
Screening Level section. The CH grade converters
are fully compliant to MIL-PRF-38534 for class H. The
HB grade converters are processed with the same
screening as the CH grade, but do not have class H
element evaluation as required by MIL-PRF-38534.
These two grades are fully tested and operate over the
full military temperature range without derating of output
power. A commercial grade is also available.
Variations in electrical, mechanical and screening
requirements can be accommodated. Extensive
computer simulation using complex modeling allows
design modifications to be examined. Contact IR San
Jose with specific requirements.

Parameter guaranteed and measured during line and load regulation tests.
Bandwidth guaranteed by design. Tested for 20 KHz to 2.0 MHz.
Capacitive load may be any value from 0 to the maximum limit without compromising dc performance. A capacitive load in excess
of the maximum limit will not disturb loop stability but may interfere with the operation of the load fault detection circuitry,
appearing as a short circuit during turn-on.
4.
5.
Parameter shall be tested as part of design characterization and after design or process changes.
An overload is that condition of load in excess of rated load but less than that necessary to trigger the short circuit protection
and is the condition of maximum power dissipation.
6.
7.
Load step transition time between 2.0 and 10 microseconds.
Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1.0 percent of VOUT at 50%
load.
8.
9.
Input step transition time between 2.0 and 10 microseconds.
Turn-on delay time measurement is for either a step application of power at the input or the removal of a ground signal from the
inhibit pin (pin 2) while power is applied to the input.
