6-MHz DC-DC Converters Offered by NXP
NXP Semiconductors' updated DC6M60xX6 family consists of 6-MHz, 650-mA step-down dc-dc converters with input voltages between 2.3 V and 5.5 V and fixed output voltages of 1.2 V, 1.5 V, 1.8 V or 2.85 V. The devices of DC6M60xX6 family are optimized for battery-driven applications. Their high efficiency of up to 95 % enables an extended battery life in all portable designs.

Buck operation at a switching frequency of 6 MHz allows using only a small low-cost 470 nH coil and two capacitors. Besides working with standard chip inductors, the DC6M60xX6 family devices also support Printed-Circuit Board (PCB) coils and air coils. Product versions with and without automatic mode selection between Pulse Frequency Modulation (PFM) and Pulse Width Modulation (PWM) are available. Optionally the devices can be switched to forced PWM mode.
These dc-dc converters feature a 1.0 x 1.4 mm BGA-style WLCSP6 package and ultra-low output voltage ripple performance of only 7 mV (typ). Quiescent current in shutdown is 0.2 µA (typ). These dc-dc converters include inrush, short circuit & over- temperature protection.

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
