Description
The RB/E series is an unregulated DC/DC converter in standard SIP7 package style.
This series has been designed to offer exceptionally high efficiency at low loads, an extended
operating temperature range and low deviation (10% to 100%). Uses include applications
with restricted energy budget and industrial applications where a high efficiency level is
required.
