Description
1 Watt
SIP7
Single Output
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.

Notes:
Note1: Efficiency is tested at nominal input and full load at +25°C ambient
Note2: Max Cap Load is tested at nominal input and full resistive load and is defined as the
capacitive load that will allow start up in under 1s without damage to the converter
