General 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 applica tions. The ML6553 can be implemented to produce regulated output voltages in two different modes. In the default mode, the output is 50 of voltage applied to VCCQ. The switching regulator is capable of sourcing or sinking up to 1A of current.

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 than passive, resistor divider termination, reducing heat by as much as 50

? Separate voltages for VCCQ and PVDD
