15 Watt XC Single Series Block Diagram
Description
These single output converters are designed for wide input
range, low noise, telecommunications, medical, industrial and
instrument applications. The extra wide input range (3:1) is
ideal for battery or unregulated input applications.
These converters are state-of-the-art 70kHz MOSFET
based designs that provide outstanding line and load regulation.
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 insures excellent
input ripple rejection and line transient response.
A logic shutdown pin to control converter operation is
included. The XC Single Series is protected from output
shorts to common by a high speed, pulse by pulse digital,
current limit circuit.
