ML6553 - Bus Termination Regulator

Description

The ML6553 switching regulator is designed to convert voltage supplies ranging from 2.0V to 3.6V into a desired output voltage or termination voltage for various applications.

The ML6553 can be implemented to produce regulated output voltages in two different modes.

Features

  • Can source and sink up to 1A.
  • Generates termination voltages for DDR SDRAM, SSTL_2 SDRAM, SGRAM, or equivalent memories.
  • Generates termination voltages for active termination schemes for GTL+, DDR, Rambus™, VME, LV-TTL, PECL and other high speed logic.
  • VL regulated to within 3% at 800mA.
  • Minimum external components. Requires no feedback compensation.
  • Fixed frequency operation for easier system integration.
  • Lower power consumption th.
