Description
The RPP40 and RPP50 series 2:1 input range DC/DC converters are ideal for high end industrial applications and
COTS Military applications where a high ambient operating temperature converter is required. Although the case
size is compact, the converters contains a built-in EN55022 Class B / FCC Level B EMC filter without the need for
any external components.
