Linear Technology has introduced the LTC4080, a multi-function IC featuring a standalone linear battery charger and a highly-efficient synchronous buck converter. The USB-compatible battery charger can charge a single-cell Li-Ion battery up to 500mA without overheating the device or surrounding components. The 300mA buck converter features selectable mode operation and synchronous rectification to achieve efficiencies up to 96%.

TDI is introducing a complete series of environmentally sealed power modules (ESPM). The first modules to be released are the efficient and ruggedized 1000 and 2700W units. These modules are designed to withstand and operate reliably in harsh environments and critical applications. The ESPM series is also electrically hardened to survive severe AC input transients.

Transistor Devices' Dynaload Division has announced the addition of Ethernet communication capabilities to its popular RBL, MCL and WCL series of programmable electronic loads.

Transistor Devices (TDI) has introduced its Signature 1000W, 1U Power Module providing -54VDC for Rectifier applications and +48VDC for Front End architectures. The modules are designed for use in 300mm or mid-plane cabinets by featuring a chassis depth of just 10.63in. They fit three-across in the matching 19in , 1RU power shelf and share up to 3000W per shelf.

New from Lincoln-based VxI Power is the Studer Compact series of inverter/chargers, which combine the functions of a sine-wave inverter, a battery charger and an automatic transfer system to manage the available power. Designed to provide reliable and silent operation, the inverter/charger connects to an AC mains supply or generator and a 12V, 24V or 48V battery.

Designed to meet NVDC-I requirements for better efficiency and longer battery life, Intersil’s ISL6257 is a narrow VDC (voltage direct current) charger controller for Li-Ion/Li-Ion polymer batteries in notebook computers. The device is the only NVDC-I charger on the market that is optimised for this application, allowing customers to run laptops at much lower battery voltages, providing better efficiency, longer battery life and improved therm...

Transistor Devices has added a 3600W power module to its Mercury series of AC to DC rectifiers / front ends. This unit employs state of the art components, topology and design techniques to achieve high efficiency and high reliability. It is ideally suited for a wide variety of outdoor and indoor Telco, Wireless/cellular and Industrial applications. Features include 220VAC input, hot bus pluggability, RoHS compliance and 93% efficiency (typical...

XP Power’s latest compact desktop AC/DC power supply, PDM60, provides Class II system protection. Safety approvals include UL609501 and EN609501 for industrial and IT applications, and UL60601-1 and EN60601-1 for medical systems. With 4000 VAC isolation and low leakage current, the PDM60 is ideally suited to both medical and commercial use. Measuring just 135 x 65 x 41 mm (5.3 x 2.5 x 1.6 inches), it has an improved power density over previous ...

As a growing number of smart phones and other handheld devices operating off a single-cell lithium-ion battery add higher levels of processing power and begin to serve as central computing platforms, users are demanding connectivity to other peripheral devices. By integrating a boost converter with a current-limiting load switch, AnalogicTech’s AAT1275 power management IC allows designers to boost voltage and provide the protection needed to ...

Linear Technology has announced the LT3475, a dual 36V, up to 2MHz step-down DC/DC converter designed to operate as a two-channel constant- current LED driver. Each channel has an internal sense resistor and dimming control, making it ideal for driving LEDs requiring up to 1.5A of current. One channel switches 180 degrees out-of-phase with the other, reducing input ripple. High output current accuracy is independently maintained for each channel ...
