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.
Bus hold makes logic more predictable
Fairchild Semiconductor has made a number of additions to its LCX family, the logic industry standard for 3.3V applications.
Compared with discrete IGBT solutions, the integrated SPM requires less than half the board space, while providing low-voltage control and high-voltage output stage rated at 10-20A at 230V AC.
The DIP-SPM comes in a small (60 x 31mm), ceramic-based transfer moulded-type package that optimises heat transfer from the IGBTs, achieving a 27% higher power rating than a conventional TO-220F package.
The high-speed high voltage control circuit (HVIC) built into the module eliminates the need for optocouplers and allows the IGBTs to be driven by a single bias supply.
This significantly simplifies the product's design and therefore reduces cost.
In addition, the smart power module's advanced current-sensing IGBT chips provide short-circuit current detection and protection.
The need for fewer parts further reduces time for system design and manufacturing and diminishes the field failure ratio.
Other features of the DIP-SPM products that benefit system designs include built-in high- and low-speed controls for user-flexibility.
Full protection features ensuring reliability, include an optional built-in thermistor for over-temperature monitoring.
For advanced current sensing, IGBT chips on the module maintain continuous monitoring of the IGBT current for highly effective short-circuit current detection.
The integrated HVIC also facilitates a single drive supply voltage to drive the device.
Divided negative DC-link terminals provide inverter current sensing.
The DIP version of the SPM enhances Fairchild's growing smart power module portfolio, which includes the previously released SPMs available in a triple inline package (TIP) for higher power motor applications.
Samples and production quantities are available now, with lead times of 12 weeks or more for larger orders.
