DC/DC Conver ter
ter
Ultra-high efficiency, 93% at full rated load current
Delivers up to 275 Watts of output power with mini-
mal derating - no heatsink required
Input voltage range: 38V – 55V suitable for 48V bus
applications
Fixed frequency switching provides predictable EMI
performance
Operational Features
Input under-voltage lockout disables converter at low
input voltage conditions
Output current limit and short circuit shutdown protects
converter and load from permanent damage
Active back bias limit prevents damage to converter
from external load induced pre-bias
Output over-voltage protection
Thermal shutdown
