DC-DC Converter Module
Features
Input voltages: 24, 48, 300 & 375 V
DC outputs: 2 V– 48 V
Programmable output: 10 to 110%
Regulation: ±0.5% no load to full load
Efficiency: Up to 90%
Max operating temp: 100°C, full load
Power density: Up to 120 W/cubic inch
Parallelable, with N+M fault tolerance
Low noise ZCS/ZVS architecture
Product Overview
These DC-DC converter modules use
advanced power processing, control and
packaging technologies to provide the
performance, flexibility, reliability and
cost effectiveness of a mature power
component. High frequency ZCS/ZVS
switching provide high power density
with low noise and high efficiency.
Applications
Off-line systems with autoranging or
PFC frontends, industrial and process
control, distributed power, medical, ATE,
communications, defense, aerospace
