California Micro Devices Expands Family of DDR Linear Power Solutions for Digital Consumer Applications
MILPITAS, California, December 12/- CM3212 Fully Integrated Dual Output DDR Linear Power Regulator
California Micro Devices (Nasdaq: CAMD), today announced the CM3212 dual output linear regulator for powering DDR (Double Data Rate) memory in digital consumer and PC peripheral applications such as digital TVs, set top boxes, DVD players and game consoles. The CM3212 features the industry's highest level of functional integration, lowest cost and smallest design footprint compared to competing solutions for DDR memory. The CM3212 integrates the VDDQ and VTT power supplies, the VREF voltage supply and a VTT enable function for implementing "Suspend to Ram" sleep mode. The integration of these features provides space savings of up to 78 percent and a 70 percent cost savings.
"Most DDR power solutions were developed for the PC rather than for digital consumer applications. They are more expensive and provide higher power than required for a typical set top box or digital TV," stated Joe Salvador, director of marketing for computing and digital consumer products at California Micro Devices. "The CM3212 linear DDR regulator is the industry's only power solution optimized for the unique cost and power requirements of powering DDR memory in digital consumer products."
Key Features
The CM3212 provides a fully integrated and complete power solution for a DDR memory system in digital consumer electronics and PC peripheral applications. It features two independent linear regulators for VDDQ and VTT, along with an integrated VREF supply. With integrated power MOSFETs, the CM3212 can source up to 2A of VDDQ current, and source or sink up to 2A of VTT current. The typical dropout voltage for VDDQ is 500mV at 2A load current.
The CM3212 also features an enable VTT pin for sleep or "Suspend to RAM"
mode. The "Suspend to RAM" mode allows for the DDR memory to be powered while suspending VTT, reducing overall system power when the system is in standby.
The CM3212 provides fast response to transient load changes. It integrates overcurrent protection with short circuit and thermal shutdown for VDDQ and VTT. The device is available in ROHS compliant lead-free TDFN-8 and SOIC packages.
Pricing and Availability
The CM3212 is sampling now with volume production scheduled for Q1 2007.
The CM3212-02SM (SOIC) is priced at US$0.54 and the CM3212-02DE (TDFN) is priced at US$0.59 each in 1,000 unit quantities.
