MP3389EF controller

Description

The MP3389EF is a step-up controller with 12-channel current sources designed for driving the WLED arrays for large size LCD panel backlighting applications. The MP3389 uses current mode, fixed frequency
architecture. The switching frequency is programmable by an external frequency setting resistor. It drives an external MOSFET to boost up the output voltage from a 5V to 28V input supply. The MP3389 regulates the current in each LED string to the programmed value set by an external current setting resistor.

AM79C972BKC datasheet

 

Description

The Am79C972 PCnet-FAST+ controller is a highly integrated 32-bit full-duplex, 10/100-Megabit per second (Mbps) Ethernet controller solution, designed to address high-performance system application requirements. It is a flexible bus mastering device that can be used in any application, including network-ready PCs and bridge/router designs. The bus master architecture provides high data throughput and low CPU and system bus utilization. The Am79C972 controller is fabricated with advanced low-power 3.3-V CMOS process to provide low operating current for power sensitive applications.

The Am79C972BKC PCnet-FAST+ controller also has several enhancements over its  predecessor, the Am79C971 PCnet-FASTdevice. In addition to integrating the SRAM on chip, it further reduces system implementation cost by the addition of a new EEPROM programmable pin (PHY_RST), an internal oscillator circuit eliminating the need for an external crystal, and the integration of the PAL function needed for Magic Packet application. The PHY_RST pin is implemented to reset the external PHY without increasing the load to the PCI bus and to block RSTto the PHY when PG input is LOW.
