MAXIM OFFERS LOWEST COST HAMMER AND ATHLON VRM/VRD DC-DC CONTROLLERS FOR DESKTOPS, NOTEBOOKS, AND SERVERS
SUNNYVALE, CA-December 3, 2002-Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX1937 and MAX1939, dual-phase, pulse-width modulation (PWM), step-down DC-DC controllers optimized for multiple generations of AMD's Athlon™ (MAX1937) and Hammer™ (MAX1939) processors.
These high-performance controllers use Maxim's proprietary Quick-PWM™ architecture, providing excellent transient response (within 300ns) and significantly reducing the number and cost of output capacitors. Additionally, their 0.75% output accuracy and fast active-voltage positioning reduce output capacitor size and cost. The MAX1937/MAX1939 offer up to 30A output-per-phase (60A total) and feature on-the-fly VID change and wide input operating voltage. These features enable the lowest cost design of CPU core supplies in desktop, mini-desktop, notebook, and server computers.
The MAX1937 and MAX1939 use 6.5V gate drivers, permitting fewer and less-expensive MOSFETs compared to 5V gate drivers in competing integrated-driver multiphase solutions. The Maxim controllers also provide remote output voltage sensing and allow for lossless current sensing, short-circuit shutdown, and overvoltage protection.
The MAX1937EEI and MAX1939EEI come in a space-saving 28-pin QSOP package. Both controllers are specified for the extended industrial temperature range (-40°C to +85°C). Evaluation boards are available in VRM and VRD form factors to speed designs. Prices start at $2.25 (1000-up, FOB USA).
