Description
The EVW020A0A, Eighth-brick low-height power module is an isolated dc-dc converters that can deliver up to 20A of
output current and provide a precisely regulated output voltage of 5.0V over a wide range of input voltages (V
IN
= 36 -
75Vdc). The modules achieve typical full load efficiency of 92%. The open frame modules construction, available in
both surface-mount and through-hole packaging, enable designers to develop cost and space efficient solutions.
Standard features include remote On/Off, remote sense, output voltage adjustment, overvoltage, overcurrent and
overtemperature protection.
