LTC3525-3.3/-5 : 400mA MicroPower Synchronous Step-up Regulators with Output Disconnect in an SC70
MILPITAS, CA – Linear Technology announces the LTC3525-3.3 and LTC3525-5, 400mA synchronous step-up DC/DC converters with true output disconnect and inrush current limiting in SC70 packages. They operate from an input voltage range of 1V to 4.5V, making them ideal for single- and multicell alkaline/NiCd/NiMH, as well as Li-Ion applications. The LTC3525 -3.3 offers a fixed 3.3V output whereas the LTC3525-5 has a fixed 5V output. The LTC3525-3.3 can deliver up to 140mA of continuous output current from dual AA alkaline cells. The LTC3525-5 can deliver up to 175mA at 5V from a 3V input. Both devices use synchronous rectification to enable efficiencies of up to 95%. Their Burst Mode® operation lowers quiescent current to only 7uA, providing maximum battery run-time in handheld applications. The combination of an SC70 package plus only 3 tiny externals provides small solution footprints as required in space constrained applications.

LTM4600: 10A DC/DC uModule Provides New Level of Power Density in a Compact Package
MILPITAS, CA – A new uModuleTM (micro-module) from Linear Technology Corporation provides designers a complete 10A switching power supply in a tiny (15mm x 15mm) footprint, low profile (2.8mm) land grid array (LGA) package. The LTM®4600 is a synchronous switchmode DC/DC step-down regulator with built-in inductor, supporting power components and compensation circuitry. The LTM4600 is the first in a new family of uModules from Linear Technology that leverages the company’s core strengths in power management and conversion. By simplifying power system development, this new high-density power supply reduces development time for a broad range of systems, including network routers, blade servers, cellular basestations, medical diagnostic equipment, test instrumentation and RAID systems.

Exar Launches XRT95L53 - EXtendAR 48M™ - The Industry's First Universal OC-48/STM-16 Multi-protocol Framer
Fremont, CA, - Exar Corporation today added EXtendAR 48M™ (XRT95L53) to its product portfolio - the industry's first universal OC-48/STM-16, Quad OC-12/STM-4 & OC-3/STM-1 multi-protocol framer. This is the first in a family of multi-protocol over SONET/SDH framers extending Exar's technology leadership into next generation metro core and transport network markets. Deployments of these highly integrated devices are enabling the convergence of triple-play services together with data over SONET/SDH. The device employs a unique set of flexible packet framing and encapsulation features combined with optimal SONET transport capabilities. This makes EXtendAR 48M™ an ideal solution for legacy systems as well as add/drop multiplexers, Optical Edge Devices (OED's), multi-service provisioning platforms and edge router applications.
