Description
Selection Chart
These single output converters are designed for ultra wide
input range low noise telecommunications, industrial, and
instrument applications. The very wide input range (4:1) is
ideal for battery or unregulated input applications while the
low noise complements even the most sensitive analog
circuitry.
