Highly efficient switching regulator is an award winner

22 February 2006 Power Electronics / Power Management

STMicroelectronics has been named in the Top 10 DC-DC 2005 Awards by Electronic Product China (EPC) magazine, for its L5973 2 A step-down switching regulator.

The highly efficient and easy-to-use device is part of ST's L597x family of monolithic regulators in small outline packages that are capable of delivering up to 2,5 A, over a wide voltage range, for use in advanced price-sensitive applications.

With its integrated power switch, the L5973 is available in the compact SO8-size HSOP8 exposed-pad package for improved heat dissipation. It operates over a wide 4,4 V to 36 V supply voltage, and its output is adjustable from 1,2 V to 35 V, making it an ideal DC-DC choice across a broad range of applications. This says the company, makes it achieve an excellent balance between high performance and low cost. Efficiency is typically 90% (5 V output from a 12 V supply).

The high switching frequency (250 kHz) and a full set of embedded protection circuits allow the size and the number of external components to be minimised. This reduces the size, cost and design time of the application, and increases reliability. The L5973 is a 'user-friendly' product which is easy to design with - even for non-specialist power conversion designers, says ST. the company also offers on-line switching regulator simulation software, in addition to evaluation boards and application notes, to help board designers shorten the design-in cycle.

ST has introduced the L597x family over the last two years to expand its long established switching regulator portfolio. While earlier products were used mainly in industrial applications and traditional power supplies, increasing demand from 'new applications' for compact regulators with 0,5 A to 2,5 A current rating is now being met by the new devices.
