Description
The R1S/E series is an unregulated DC/DC converter in fully encapsulated SMD package style. This series has been
designed to offer exeptionally high efficiency at low loads and an extended operating temperature range. Uses in-
clude battery powered supplies, green energy applications and general isolating/converting DC power where board
space and high efficiency is a premium.
