HLD SERIES - 60 WATT
Half-Brick
DESCRIPTION
The HLD series are through-hole mount,
Half-brick, Low
profile,
Dual
output DC/DC high density converters. The HLD series
provides onboard conversion of telecom and datacom input
voltages to isolated low output voltages without the need for a
heatsink. The HLD series is well suited for distributed power
architectures, telecom equipment, and LAN/WAN and data
process applications.
FEATURES
• Single-board, multi-layer
design
• Planar magnetics
• Fully automated - minimal
‘touch time’
• Two independently
regulated outputs
• Can start into high
capacitive load
• Low profile
• Standard half-brick size and
pinout
