LAMBDA ADVANCED ANALOG INC.

PRELIMINARY

AHV2800 Series

Hybrid - High Reliability

DC/DC Converters

DESCRIPTION

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 (P.I.)

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. Variations in electrical, mechanical

and screening can be accommodated. Contact

Lambda Advanced Analog for special requirements.

The AHV series of DC/DC converters are designed

to replace the AHE/ATO family of converters in

applications requiring compliance to MIL-STD-704A

through E, in particular the input surge requirement

of 80 volts specified in MIL-STD-704A.

The

converters are designed to withstand transient input

voltage of 80 volts. No input voltage or output

power derating is necessary over the full military

temperature range.

These converters are packaged in an extremely

rugged, low profile package that meets all

requirements of MIL-STD-883 and MIL-PRF-38534.

Parallel seam weld sealing and the use of ceramic

pin feedthru seals assure long term hermeticity after

exposure to extended temperature cycling.

FEATURES

The basic circuit is a push-pull forward topology

using power MOSFET switches.

switching frequency is 500 KHz. A unique current

injection circuit assures current balancing in the

power switches. All AHV series converters use a

single stage LC input filter to attenuate input ripple

current. A low power 11.5 volt series regulator

provides power to an epitaxial CMOS custom pulse

width modulator integrated circuit.

This single

integrated circuit provides all PWM primary circuit

functions. Power is transferred from primary to

secondary through a ferrite core power transformer.

An error voltage signal is generated by comparing a

highly stable reference voltage with the converter

output voltage and drives the PWM through a

unique wideband magnetic feedback circuit. This

proprietary feedback circuit provides an extremely

wide bandwidth, high gain control loop, with high

phase margin. The feedback control loop gain is

insensitive to temperature, radiation, aging, and

variations in manufacturing. The transfer function of

the feedback circuit is a function of the feedback

transformer turns ratio which cannot change when

subjected to enviromental extremes.
