The JHW dual output –series from Tyco Electronics is
a new generation of high efficiency dual output dc-dc
converters designed for optimum flexibility utilizing flex
load and wide output voltage adjustment trim. In
addition, the JHW dual-series supports future migration
of semiconductor and microprocessor supply voltages
down to 0.8V.
