Dual-output buffer for DDR SDRAM modules
Fairchild Semiconductor has introduced a dual-output registered buffer for 184-pin, 2.5V PC200/PC266, 72bit-wide registered double data rate (DDR) SDRAM modules.
Power consumption and space efficiencies are achieved through the use of a 650V BCDMOS process resulting in fewer external components and impressive reduction in PC board space requirements.
The FSDH0165 is a self-biased and protected linear control current-to-duty cycle convertor with an open drain output.
The device operates from 6.7 to 21V at a frequency of 100 kHz.
It is equipped with built-in start-up switch eliminating the need for an external start up resistor.
Other features include autorestart to minimise power consumption in standby mode, overload protection, overcurrent protection and internal thermal shutdown protection.
The DIPH package enhances thermal conductivity by connecting a single, wide lead to two ground pins.
When used in combination with the Fairchild FAN7563 controller IC, the FSDH0165 provides a space saving, two-IC solution for low-power battery-charging applications.
An application note is available.
