HYBRID HIGH-RELIABILITY
DC-DC CONVERTER
Description
The ATW28300S DC-DC converter features high
power density and an extended temperature range
for use in military and industrial applications.
Designed to MIL-STD-704D input requirements, this
device operates with a nominal 28VDC input with an
adjustable output of 150 to 300V via external
potentiometer. The circuit design incorporates a pulse
width modulated push-pull topology operating in the
feed-forward mode at a nominal switching frequency
of 270KHz. Input to output isolation is achieved
through the use of transformers in the forward and
feedback circuits.

Features
n 18V to 40VDC Input Range (28VDC Nominal)
n Short Circuit and Overload Protected
n 22.8W/in3 Power Density
n 30W Output Power
n Adjustable Output Voltage
n Fast Loop Response
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.
n Superior Transient Characteristics
n Operating Temperature Range of
-55°C to +125°C
n Popular Industry Standard Pin-Out
n Resistance Seam Welded Case for Superior
Long Term Hermeticity
Manufactured in a facility fully qualified to MIL-PRF-
38534, this converter is available in four screening
grades to satisfy a wide range of requirements. The
CH grade is fully compliant to the requirements of
MIL-PRF-38534 for class H. The HB grade is
processed and screened to the class H requirement,
but may not necessarily meet all of the other MIL-
PRF-38534 requirements, e.g., element evaluation
and periodic inspection not required. Both grades
are tested to meet the complete group “A” test
specification over the full military temperature range
without output power deration. Two grades with more
limited screening are also available for use in less
demanding applications. For screening options, refer
to device screening table. Variations in electrical,
mechanical and screening can be accommodated.

Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1.0% of VOUT at 50% load.
Turn-on delay time measurement is for either a step application of power at the input or the removal of ground signal from the
Enable pin (pin 2) while power is applied to the input.
3
An overload is that condition with a load in excess of the rated load but less than that necessary to trigger the short circuit
protection and is a condition of maximum power dissipation.
4

6
Above +125°C case, derate output power linearly to 0 to +135°C case.
Transition time >10µs.
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 may disturb loop stability and may interfere with the operation of the load fault detection circuitry, appearing
as an overload during turn-on.

Bandwidth guaranteed by design. Tested for 20KHz to 1.0MHz.
Parameter guaranteed by line and load regulation tests.
Parameter shall be tested as part of design characterization and after design or process changes. Thereafter parameters shall be
guaranteed to the limits specified in this table.
10 Output voltage can be adjusted to the range of 150V to 300V with an external 1KOhms trim pot. The trim pot shall be connected
to pin 5 (Output Adjust 1) and pin 6 (Output Adjust 2).
