LTC4080: 500mA Standalone Li-Ion Battery Charger plus Synchronous Buck Converter in 3mm x 3mm DFN MILPITAS, CA – Linear Technology Corporation introduces 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%. The device is designed to work with supplies up to 5.5V, including those within USB specifications and from 5V wall adapters. Its 3mm x 3mm DFN package ensures a tiny solution footprint for space- constrained, smaller battery capacity powered handheld applications such as wireless headsets, Bluetooth devices, portable MP3 players, and multi-function wristwatches.

LTC2928: Quad Power Supply Sequencer & Supervisor Provides Simple Configuration & Extensive Diagnostics Without Software MILPITAS, CA – The LTC2928 quad supply sequencer and supervisor from Linear Technology offers the flexibility to configure the power supply turn-on and turn-off sequence, monitor the supplies and diagnose supply failures. The device’s simple pin-configuration approach to sequencing requires no firmware and allows the four supplies to be placed in any combination of eight time positions with configurable delay between each. The comparator thresholds during the sequence-up, monitoring and sequence-down phases can be specific to each phase. The comparator outputs are encoded into four digital outputs that provide diagnostics for the type of fault (sequence, under-voltage, external controller or external fault) and the channel that failed. Over-voltage faults are signaled separately and may be optionally tied to the bidirectional FAULT pin to cause a shutdown. These timing, threshold and diagnostic options are configured with only a few external components. Leer la noticia completa Martes, 20 Junio, 2006 - 12:13
