ML6553 Overview
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.
Key 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
