DESCRIPTION
The µV300 Series are high density DC-DC
converters designed for use in telecom and
other centralized modular and distributed
power applications. The µV300 Series use
metal PC boards, planar transformers, and
surface mount construction to produce up
to 252 watts in a tiny package.
FEATURES
• Miniature Size
• High Density – Up to 58 W/in.3
• Constant Frequency – 370KHZ
• Parallelable with Current Sharing
• Fault Tolerant – n+m Redundancy
• Extremely Low Thermal Resistance
• Output Good Signal
• Optional Sync Pin
• Non-Shutdown OVP
• Logic On-Off
• Thermal Protection
• Current Limit/Short Circuit Protection
• UL/CSA/TUV/CE MARK Approvals
