Sipex Corp. (Milpitas, CA), a provider of high-performance, analog integrated circuits, announced its SP7652, the first of Sipex’s new PowerBlox™ family of high-current, high-voltage, ultra-miniature, dc-dc buck regulators. The PowerBlox family will consist of five products that range from 3 A to 8 A output current, and from 300 kHz to 1.2 MHz switching frequency.
The SP7652, the first product of the family, is a 600 kHz, 6 A, step-down regulator capable of handling up to 28 V input and delivering output voltages as low as 0.8 V. By integrating the highest efficiency switches with a resistance of only 15 milliohms, the SP7652 outperforms all competing solutions with over 92% efficiency at full load. Other device features include programmable soft-start, over-temperature protection, dual under-voltage lock-out thresholds, and short-circuit protection. The part is packaged in a custom DFN assembly, measuring 7 mm x 4 mm, with three integrated heatsinks for thermal management. The SP7652 can be used in a wide variety of applications due to its programmability and wide input-voltage range of 2.5 V to 28 V.
The SP7652 samples are available now, as well as an evaluation board. 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. Pricing for the SP7652 begins at $2.92 in 10,000-piece quantities.
