The ESTW010A0A, Eighth-brick low-height power module is an isolated dc-dc converters that can deliver up to 10A
of output current and provide a precisely regulated output voltage of 5.0V over a wide range of input voltages (VIN =
36 - 75Vdc). The modules achieve typical full load efficiency of 91%. The open frame modules construction, available
in both surface-mount and through-hole packaging, enable designers to develop cost and space efficient solutions.
