Description
The low voltage FW single output converters are designed for
ultra wide input range, low noise industrial and instrument
applications requiring low input operating voltages. The wide
input range (3:1) is ideal for battery or unregulated input
applications.
These converters are state-of-the-art 100 kHz designs that
provide outstanding line and load regulation with efficiencies
approaching 82%.
The single outputs are regulated with a high loop gain
current mode control method that provides linear regulator
type performance with a true, high efficiency switching DC/DC
topology. The large amount of loop gain also insures excellent
input ripple rejection and line transient response.
All converters in this series are protected from output short
circuit, thermal overload and overvoltage transients on the
input and output.
Low noise outputs, 70 mV P-P maximum
Very low reflected ripple, 50 mA P-P maximum
Excellent regulation from no load to full load 0.2%
maximum
Excellent line regulation, 0.1% maximum
Efficiencies to 82%
Six-sided shielded low thermal gradient copper case
Five Year Warranty
