5 to 7.5 Watt FW Single Series DC/DC Converters
Description
Features
!
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.
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
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
typeperformancewithatrue, highefficiencyswitchingDC/DC
topology. The large amount of loop gain also insures excellent
input ripple rejection and line transient response.
