Description
These single output converters are designed for low noise,
telecommunications, industrial and instrument applications.
Their wide input range (2:1) makes them ideal for battery or
unregulated input applications.
These converters are state-of-the-art 120 KHz MOSFET
based designs that provide outstanding line and load regulation
with efficiencies approaching 85%.
The outputs are regulated by 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.
The FW Single converters are protected from output shorts
to common by a high speed, pulse-by-pulse, digital, current
limit circuit.
The input and output are overvoltage protected with transient
suppressor diodes. UL recognition under specification numbers
1459 and 1012 is currently pending.
