Sunnyvale, Calif.Maxim Integrated Products has introduced the MAX15048/MAX15049, low-cost, three-output, synchronous step-down controllers with tracking (MAX15048) or sequencing (MAX15049) options.
Designed to meet the tight tolerances of small-geometry logic devices, these controllers drive external MOSFETs to deliver a regulated 0.6V to 19V output voltage and up to 15A of load current per output. Additionally, integrated tracking/sequencing allows customers to seamlessly control core and I/O voltages.
Applications include a variety of high-reliability power-supply systems such as those in telecom, networking, storage, and server equipment.
The MAX15048/MAX15049 operate from a wide 4.7V to 23V input range to support low-cost battery packs, as well as the latest 40nm ASICs. Each PWM section operates from a programmable switching frequency (200kHz to 1.2MHz). Operating at 1.2MHz and 120 degrees out-of-phase increases the input capacitor ripple frequency to 3.6MHz. This reduces the RMS input ripple current and size of the input bypass capacitor.
The MAX15048/MAX15049 are offered in a thermally enhanced, 5mm x 5mm, 32-pin TQFN package, and are fully specified over the -40°C to +85°C extended temperature range.
Pricing: Starts at $3.10 (1000-up, FOB USA). Evaluation kit is priced at $125.
