SUNNYVALE, CA-January 8, 2009-Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX15034, a high-performance, dual-output, synchronous step-down controller capable of driving external MOSFETs to deliver two 25A outputs or a single 50A output. This flexibility allows the device to be used for multiple design platforms, thereby reducing inventory and cost. Additionally, the MAX15034 can operate from a 4.5V to 5.5V or 5.5V to 28V input range, allowing it to be used in both 5V- and 12V-bus applications. Optimized for designs requiring a high output current, this device is ideal for computing, telecom, networking, storage, and server equipment.
The MAX15034 offers powerful programming features to maximize flexibility. Programmable features include output voltage (0.6V to 5.5V), switching frequency (100kHz to 1MHz), current-limit threshold, and the external compensation network. These adjustable features allow each design to be optimized in terms of size, performance, and cost.
To maximize space and cost savings, the device employs an average current-mode scheme that provides current-limit and current-sharing accuracy of better than 10% between phases. The accurate current limit eliminates the need for oversized external MOSFETs and inductors.
Additional MAX15034 features include: the ability to start up monotonically when the output has a prebiased voltage; two enable inputs with accurate turn-on thresholds to allow output-voltage sequencing; external frequency synchronization; and thermal-shutdown and hiccup-mode protections.
The MAX15034 is available in either a 28-pin TSSOP or a 28-pin TSSOP with exposed pad. Both versions are fully specified over the -40°C to +125°C automotive temperature range. Prices start at $2.56 (1000-up, FOB USA).
An evaluation kit is available to speed designs-contact the factory for details.
