3A Bus Termination Regulator
ML6554 3A Bus Termination Regulator February 2005 ML6554 3A Bus Termination Regulator Features Description ■Can source and sink up to 3A, no heat sink required The ML6554 switching regulator is designed to convert voltage supplies ranging from 2.3V to 4V into a desired output voltage■Integrated Power MOSFETs or termination voltage for various applications. The ML6554 can ■Generates termination voltages for DDR SDRAM, be implemented to produce regulated output voltages in two dif- SSTL-2 SDRAM, SGRAM, or equivalent memories ferent modes. In the default mode, when the V pin is open, REF ■Generates termination voltages for active termination the ML6554 output voltage is 50% of the voltage applied to schemes for DDR SDRAM, GTL+, Rambus, VME, V . The ML6554 can also be used to produce various user- CCQ LV-TTL, HSTL, PECL and other high speed logic defined voltages by forcing a voltage on the VREF pin. In this IN ■V input available for external voltage divider REF case, the output voltage follows the input VREF voltage. The IN ■Separate voltages for V and PV switching regulator is capable of sourcing or sinking up to 3A of CCQ DD current while regulating an output V voltage to within 3% or■Buffered V output TT REF less. ■V of ±3% or less at 3A OUT The ML6554, used in conjunction with series termination resisi-■Minimum external components tors, provides an excellent voltage source for active termination ■Shutdown for standby or suspend mode operation schemes of high speed transmission lines as those seen in high ■0° to +70°C and -40° to +85°C temperature ranges available speed memory buses and distributed backplane designs.
