Description
The ESTW025A0F series, Eighth-brick power modules are isolated dc-dc converters that can deliver up to 25A of output
current and provide a precisely regulated output voltage over a wide range of input voltages (Vin = 36 -75V
dc
). The
module achieves typical full load efficiency of 92% at 3.3V
dc
output voltage. The open frame modules construction, available
in both surface-mount and through-hole packaging, enable designers to develop cost- and space-efficient solutions.
RoHS Compliant
