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 3A to 80A output current to satisfy

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 side of a printed circuit board

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 market faster.
