Original Press Release:
Micrel Launches a New Pin-Configurable, 19V, 5A DC/DC Converter Offered in a Tiny Package for Communication, Enterprise, Industrial Systems
SAN JOSE, Calif. – Micrel, Inc. (Nasdaq: MCRL), an industry leader in high performance linear and power solutions, LAN and timing and communications solutions, today announced the availability of the MIC24046-H, a high efficiency (>90 percent peak), pin-configurable 5A synchronous buck converter in a tiny 3mm x 3mm QFN package. The device features pin selectable output voltage, switching frequency and current limit settings which improve design flexibility and eliminates multiple external components. The solution targets end equipment such as network switches/routers, servers, storage, base stations, FPGA and DSP power as well as factory automation and security cameras. The MIC24046-H is available in volume with pricing starting at $1.33 for 1,000 quantities. Samples can be ordered on line at: http://www.samplecomponents.com/scripts/samplecenter.dll?micrel.
"New generation Telecom and Datacom systems are pushing the limits of power density requirements such that applications now require a flexible and high performance DC-DC solution in a smaller footprint," stated Brian Hedayati, vice president of marketing for high performance and linear power solutions at Micrel. "Micrel's MIC26046-H provides high efficiency and design flexibility. The output voltage, current limit and switching frequencies are pin-selectable and do not require external components thereby dramatically simplifying the design and allowing the same device to be used for multiple power supply rails."
The MIC24046-H operates over a wide input voltage range of 4.5V to 19V making it ideal for distributed 12V point-of-load applications. The solution offers three settings for switching frequency (400kHz, 565kHz, or 790kHz) and the output voltage can be selected from 0.7V to 3.3V via nine different settings. An internal divider is used for true 1 percent V(OUT) accuracy setting from 0.7V to 1.2V. The current limit can be selected to support three application requirements (3A, 4A, or 5A). The MIC24046-H provides hiccup-mode short circuit protection. Other features include internal soft-start, safe pre-biased start-up, and thermal shutdown. The MIC24046-H is available in a 20-pin, 3mm × 3mm QFN package and has a junction temperature range of -40-degC to +125-degC. This is the first of a series in a product family.
