FP6137D

fitipower integrated technology lnc. FP6137D Peak 2A Bus Termination Regulator Description The FP6137D linear regulator is designed to provide the transient peaks up to 2A sourcing or sinking capability for DDR SDRAM bus termination application. The output voltage can track half of input power by two external voltage divider resistors. The FP6137D provides current limiting in both sourcing/sinking mode and thermal shutdown function which protects the excessive heating due to high current and high junction temperature. The FP6137D is available in the SOP-8 (Exposed Pad) package. Features ● Peak 2A Source or Sink Current ● Power MOSFET Integrated ● Low Output Voltage Offset ● Current Limiting Protection ● Thermal Shutdown Protection ● Adjusted Output by External Resistors ● Shutdown for Standby or Suspend Mode ● RoHS Compliant Applications ● DDR-I and DDR-II Bus Termination Voltage ● SSTL-2 and SSTL-3 Termination ● Active Termination Buses Pin Assignments SP Package (SOP-8) VIN GND REFEN VOUT 18 27 3 GND 6 45 NC NC VCNTL NC Figure 1.
