Introduction
The AEE low power high efficiency series of DC-DC
converters is one of the most cost effective options
available in component power. The series uses an
industry standard package size and pinout configu-
ration, provides trim functions.
AEE low power high efficiency converters come in
24V or 48V input versions, each of which uses a 2:1
input range; 18V to 36V for the 24Vin versions, and
36V to 75V for the 48Vin versions. Outputs are iso-
lated from input and the converters are capable of
providing up to 15 watts of output power.
At start up, input current passes through an input fil-
ter designed to help meet CISPR 22 level A radiat-
ed emissions, and Bellcore GR1089 conducted
emissions. A fault clearing device such as a fuse
should be used in line with the input to the module.
The AEE low power high efficiency converters are
pulse width modulated (PWM) and operate at a
nominal fixed frequency of 300kHz (250kHz for
AEE01B48). Feedback to the PWM controller uses
an opto-isolator, maintaining complete isolation
between primary and secondary. Caution should be
taken to avoid ground loops when connecting the
converters to ground.
