PMICs enable smaller design of DC/DC converters, LDOs Product News 4/30/2007 Post a comment Maxim Integrated Products introduced the MAX8667/MAX8668, a 4-channel power-management ICs (PMICs) in a 9 mm2 TQFN package. These PMICs minimize total design size by integrating two step-down DC/DC converters and two low-input, low-dropout regulators (LDOs), as well as all feedback networks.

The critical mass of green Power DesignLine Blog 4/27/2007 Post a comment Have we hit a critical mass in awareness about our use of energy? What are some of the efforts being made to reduce energy consumption and why will they succeed?
Okay, so this blog only presents a few shining stars of the green movement - and why you should care.
MOSFETs reduce heat generation in servers, notebook computers Product News 4/23/2007 Post a comment NEC Electronics America developed two metal-oxide-semiconductor field-effect transistor (MOSFET) families. The µPA273xUT1A family is designed for use in the protection circuitry of lithium-ion (Li-Ion) batteries for notebook PCs, and is designed to help prevent heat generation and explosions which may result from Li-Ion battery overcurrent.
Selecting the best topology for white LED drive electronics Design How-To 4/22/2007 Post a comment A move to LED technology for general illumination applications could greatly reduce energy consumption. But it's not just a simple replacement because designers must be aware of space constraints, thermal considerations, and EMI. This article tells you how to deal with each of these challenges.
White-LED drivers feature inductive boost converter Product News 4/19/2007 Post a comment Sipex released the latest addition to their family of white-LED drivers for the portable market, the SP6415. The device features an inductive boost converter powering two independent drivers for driving the white-LED main panel backlighting and powering the OLED sub-display or additional white LEDs.
V-I chip bus converter offers 95% efficiency Product News 4/18/2007 Post a comment Vicor Corporation developed a high-voltage V-I chip bus converter with a power density of greater than 1000 W/in3. Designated B384F120T30, this BCM module is a high-efficiency (>95%), sine-amplitude converter (SAC) operating from a 360-400 Vdc primary bus to deliver an isolated low-voltage secondary.
POL converters deliver output with no thermal derating up to 20 A Product News 4/16/2007 Post a comment FDK Corporation enhanced their Senpai series of non-isolated point-of-load (POL) converters with the addition of the FPLR05SR75 series of dc/dc converters. Operating from a 2.4 V to 5.5 Vdc input bus, these converters deliver up to 20 A of output current with strong thermal performance; no derating is needed up to 85°C under natural convection.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
