An ISL8205MEVAL1Z evaluation can be purchased for $69 USD each. For more information, please visit: www. intersil.com/products/ISL8205m. The ISL8202M power module is available now in a 4.5mm x 7.5mm, 22-lead QFN package and is priced at $2.79 USD in 1k quantities. An ISL8202MEVAL1Z evaluation can be purchased for $69 USD each. For more information, please visit: www. intersil.com/products/ISL8202m. The ISL8205M and ISL8202M complement the highly popular dual-channel 3A/single-channel 6A ISL8203M in Intersil’s low- voltage product line. They join a comprehensive family of analog and digital power modules that support 1V to 80V input voltage rails and

market faster. For more information, samples and an evaluation module, visit www.ti.com/tps54a20-pr-eu. The TPS54A20 features a unique two-phase, series-capacitor DC/ DC buck topology that merges a switched-capacitor circuit with a multiphase buck converter. This capacitive conversion technology enables efficient, high-frequency operation and measures as much as seven times smaller than conventional converters. For a quick introduction, watch the video “How to decrease inductor size in a 10-A DC/DC converter design” and read the white paper, “Breakthrough power delivery for space- constrained applications.” Read the application note “Introduction to the Series Capacitor Buck Converter” that analyzes the technology and presents example results for a 12-V input, 1.2-V/10-A output application demonstrating higher peak efficiency than a conventional buck converter, while operating at four times higher switching frequency. TPS54A20 key features and benefits Tiny solution: Small HotRod™ quad flat no-lead (QFN) packaging and inexpensive, tiny 2- to 5-MHz inductors enable a 131-mm2 solution size that consumes 50 percent less area than similar 500- kHz DC/DC converter designs. Read the blog post, “No small matter: How to reduce voltage regulator size.” Low profile: Measuring less than 2 mm in height, the reduced size, weight and bill of materials (BOM) allows placement of tiny 10-A voltage regulators on the back

3A to 80A output current to satisfy a broad range of applications. For more information on Intersil’s power module portfolio, please visit: www. intersil.com/powermodules.

TI unveils industry’s highest power density 12-V, 10-A, 10-MHz DC/DC converter Ultra-small SWIFT™ step-down converter features unique topology to achieve four times higher current density Texas Instruments (TI) (NASDAQ: TXN) today introduced the industry’s first 12-V, 10-A, 10-MHz series-capacitor buck converter that achieves more than 50 A/cm3 in current density, which is four times higher than any other 12 V power management component or solution available today. The unique topology of the TPS54A20 SWIFT synchronous DC/DC converter enables high-frequency operation at up to 5 MHz per phase without special magnetics or compound semiconductors, which designers can use for 8-V to 14-V input and 10-A output applications. By using the step-down converter together with TI’s WEBENCH® Power Design tool, engineers can get their space- and height-constrained point-of-load (POL) telecom and networking power-supply designs to
