Voltage regulator ICs provide system voltage regulation and bus termination for SDRAM and chipsets. N-Channel FET synchronous buck regulator controller is optimized for wide input voltage range with up to 400KHz voltage mode PWM control architecture; current limit protection support without extra current sensing resistor. Adaptive non-overlapping MOSFET gate driving minimizes shoot-through and increases efficiency. Dual mode Active Bus Terminator ICs provide the termination voltages for DDR SDRAM and system chipset.

• Dual mode active DDR SDRAM and Chipset
  Bus Termination up to 3Amp
• N-FET only with non-overlapping gate driving circuit
• Over current protection with no extra current
  sensing resistor
• Fixed and variable PWM frequency

• Low cost single chip solution
• Dual mode active terminator reduces component type
• N-FET only design improves energy efficiency and
  P-FET sourcing issue
• Lower cost in over-current protection circuit
• Flexible choice of PWM Freq: fixed for lowest
  cost; variable for performace

• DDR SDRAM Active Bus Termination and Voltage Regulator for:
  • Desktop PCs
  • Graphics Cards
  • Set Top Boxes
  • Cable Modems
• General purpose DC-DC converter
