Quarter Brick DC/DC Converter

FDK Corporation (Sunnyvale, CA) has introduced a new high power regulated quarter brick to its Sensei Series of isolated DC/DC converters. The FPQR48T5R050 converter provides 50 Amperes (A) of output current (250 Watts) with outstanding thermal performance. This converter is designed for Intermediate Bus Architecture (IBA) and Distributed Power Architecture (DPA) in telecommunications, WiMAX, data processing, computing, and storage applications that require a regulated 5V distribution bus. The FPQR48T5R050 converter operates from a 36 VDC to 75 VDC input and provides a tightly regulated 5 VDC output with an efficiency in excess of 92.5%. It is offered in a 2.30" x 1.45" x 0.555" (58.4mm x 36.8mm x 14.1mm) industry-standard quarter brick footprint and pin-out.

Switch-on-a-Chip ICs

Micrel (San Jose, CA) has launched the KSZ8895/8875/8864 series of low- power, highly integrated, 4/5-port Layer-2 switch-on-a-chip ICs. Leveraging Micrel’s latest green physical transceiver and switch technology, the product family achieves a 50 percent reduction in power consumption compared to the previous generation and features advanced power management and sophisticated Quality of Service (QoS) capabilities. The devices support a single 3.3V power supply with an internal 1.2V LDO, with options for 3.3V, 2.5V or 1.8V IO voltages. Further power savings are supported by advanced power management, including the device’s “Energy Detect Power Down” mode. This mode is activated when the cable is unplugged, and the “slow oscillator” mode is activated when the device is not in use.
