Sipex Debuts New SP7655 DC-DC Buck Regulators

Sipex Corp. (Milpitas, CA), a provider of high-performance, analog integrated circuits, announced its new SP7655, which expands the new PowerBlox™ family of high-current, high-voltage, ultra-miniature, dc-dc buck regulators. The part is packaged in a custom DFN package with three integrated heatsinks for thermal management. The packaging technology produces a small 8 A component, measuring 7 mm x 4 mm.

The SP7655 is a 300 kHz, 8 A step-down regulator capable of handling up to 28 V input and delivering output voltages as low as 0.8 V. By integrating high efficiency switches with a resistance of 15 millihms, the SP7655 performs with over 95% efficiency. Other features include programmable soft-start, over-temperature protection, dual under-voltage lock-out thresholds and short-circuit protection. Due to its wide input voltage range of 2.5 V to 28 V, the SP7655 can be used in a wide variety of applications, such as PC motherboards, storage area networks, plasma televisions, bar code scanners, routers and VGA cards.

Samples of the SP7655 are available now. Pricing for the SP7655 begins at $3.50 in 10,000-piece quantities. The part is rated over the industrial temperature range of -40 °C to +85 °C and is housed in a 7 mm x 4 mm DFN package with three independent heatsinks.
