CM3121 Overview
The CM3121 provides an integrated power solution for DDR-I and DDR-II memory systems in consumer electronics applications. The CM3121 is ideal for a 2.8V to 3.6V supply for DDR-I memory and 2.2V to 2.8V for DDR-II memory.
CM3121 Key Features
- Ideal for DDR-I (2.5VDDQ) and DDR-II (1.8VDDQ)
- Lowest system cost and smallest footprint with just two external output capacitors
- Two linear regulators: -V regulator with a maximum output current .. DDQ of 1.5A shared by DRAM and VTT regulator
- source-sink VTT regulator with maximum output current of 0.5A (DDR-I) or 0.3A (DDR-II)
- Fault output indicates overcurrent condition in either regulator, under voltage lock-out and overtemperature condition
- Reverse current protection if host is powered off
- PSOP-8 package with integrated heat spreader
- Lead-free versions available
