Description
These converters provide low noise bipolar outputs from a
wide range of input voltages. The converters鈥?small 2.02" x
1.62" size makes them ideal for telecommunications,
instrumentation or industrial control applications.
The dual outputs are cross regulated with a high loop gain
current mode control method that provides good regulation
with a true, high efficiency switching DC/DC topology. The
large amount of loop gain insures excellent input ripple
rejection and line transient response.
Also included is a logic (open collector TTL / CMOS
compatible) shutdown pin to control converter operation.
The modules in the TC Dual Series are protected from
output shorts by a high speed, pulse-by-pulse, digital current
limit circuit and a thermal overload sensing circuit.
The input and output are overvoltage protected.
