SRCA-16S10L

ISOLATED DC/DC CONVERTERS 48 Vdc Input 9.6 Vdc/16 A Output, 1/16 Brick Bus Converter SRCA-16S10L • • • • • Isolated Fixed Frequency High Efficiency High Power Density Low Cost RoHS Compliant • • • • • Rev.A Input Under Voltage Lockout Input Over Voltage Shutdown OCP/SCP Thermal shutdown Remote On/Off Description The SRCA-16S10L is an isolated dc/dc bus converter that operates from a nominal 48 Vdc source. This converter is intended to provide isolation and step down to generate an intermediate bus for the purpose of powering non-isolated Point-of-Load (POL) converters. This unit will provide up to 160 W of output power from a nominal 48 Vdc input. This unit is designed to be highly efficient and cost effective. The downstream POL converters will provide the precise regulation required by the load. Features include remote on/off, over current protection and under-voltage lockout. This converter is provided in an industry standard sixteenth-brick package. Part Selection Output Voltage 9.6 V Input Voltage 36 V - 60 V Max. Output Current 16 A Max. Output Power 153 W Typical Efficiency 95% Model Number Active Low SRCA-16S10L Notes: 1. Add “G” suffix at the end of the model number to indicate Tray Packaging. 2. All part numbers above indicate RoHS 6. Change the second letter "R" to "7" for RoHS 5 part numbers.
