DESCRIPTION
The µV48 Series are high density DC-DC
converters designed for use in telecom and
other centralized modular and distributed
power applications. The µV48 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
• UL/CSA/TUV APPROVALS
• Non-Shutdown OVP
• Logic On• Thermal Protection
• Current Limit/Short Circuit Protection
