The new buck-boost regulators’ wide input voltage range of 1.8V to 5.5V supports multiple battery topologies, and their wide output voltage range of 1V to 5.2V combined with 3A output current provide the ultimate in design flexibility. The ISL91128 also features I2C programmable dynamic output voltage adjustability, which eliminates feedback resistors and allows the reuse of the same design for multiple output voltage needs. “Hand-held device designers are constantly challenged to create smaller, more efficient products whether it is the latest wearable, a portable medical device or next- generation smartphone,” said Andy Cowell, senior vice president of Mobile Power Products at Intersil. “Intersil specializes in providing the most efficient power delivery with excellent transient response. Our latest buck- boost regulators leverage generations of experience in the most demanding mobile applications to provide customers with extended battery life in a compact, easy- to-use package.” Key Features and Specifications of ISL91127 and ISL91128 • 30uA typical quiescent current: the lowest of any high current buck-boost in the industry • Up to 96% efficiency (PVIN = 3.6V, Vout = 3.4V~4V, Iout = 200mA) • Output current up to 3A in boost mode (PVIN = 3V, Vout = 3.3V) • Input voltage can range from 1.8 to 5.5V, output voltage can be adjustable or fixed at 3.3V • Full protection for under-voltage, short-circuit, and thermal faults to ensure safe operating conditions and reliable system operation • ISL91128 offers I2C dynamic voltage adjustability for output voltage, and ringing suppression for superior EMI performance The ISL91127 and ISL91128 can be combined with the ISL9003A, ISL9016, ISL9021A, and ISL9001A LDOs to support multiple output rails with improved ripple. They also work with the ISL9113 sync boost converter and ISL91133 boost regulator if additional higher voltage rails are required, and lower voltage rails are supported with the ISL9104 and ISL9103 sync buck converters.

The ISL91127 is also available in a 20-bump, 2.15mm x 1.74mm WLCSP package priced at $1.25. The ISL91127IRN-EVZ fixed 3.3V evaluation board and ISL91127IRA-EVZ adjustable voltage evaluation board

STMicroelectronics Introduces New Super- Junction MOSFETs including World’s First 1500V Device in TO-220FP Wide Creepage Package STMicroelectronics has introduced a portfolio of TO-220 FullPAK (TO-220FP) wide creepage power transistors, including the world’s first 1500V super-junction MOSFET in this new important arcing-resistant package. The TO-220FP wide creepage package is ideal for the power transistors of open-frame power supplies commonly used in equipment such as television sets and PCs, which are vulnerable to surface contamination by dust and particles that can cause high-voltage arcing between transistor terminals. The new package’s extended lead spacing of 4.25mm eliminates the special potting, lead forming, sleeving, or sealing needed to prevent the arcing when using conventional packages with 2.54mm lead spacing. Power-supply manufacturers can now meet applicable safety standards and minimize field failures without applying these additional processes, thereby simplifying manufacturing and enhancing productivity. While providing superior arcing resistance, TO-220FP wide creepage retains the outstanding electrical properties of the popular TO-220FP. Moreover, similar outer dimensions help streamline design-in and ensure compatibility with established assembly processes. ST developed the TO-220FP wide creepage package by collaborating with its customer SoluM, a leading power manufacturer based in Korea. SoluM is using the
