Module regulates voltage for Pentium P55C processor.

The MP55C voltage regulator fits into existing socket 7 headers and powers Pentium P55C processors without changes to the board. Because the P55C is the first variant to use split voltage planes—I/O requires 3.3V, and the CPU core requires a lower voltage—it adds another voltage requirement to the motherboard. The MP55C gives you the flexiblity to use either the P54C or P55C on the same motherboard. The module combines the regulator with a heatsink, capacitors, resistors, and 30-pin connector in an Intel-specified form. The MP55C costs $15 (1000). Semtech Corp, Newbury Park, CA. (805) 498-2111.

Charger accommodates wide range of NiCd, NiMH batteries.

Using accurate negative delta-voltage sensing, the HEC66 battery charger for NiCd and NiMH battery packs delivers 1.25A pulsed constant current over a voltage range of 5 to 24V, depending on the model. A refresh mode, which is activated by the push of a button, discharges and monitors the battery pack to a voltage of 0.9 to 1.0V/cell, at which time it switches to a high-charge mode. LED indicators show charger status, including shorted cell, open battery, discharge mode, high charge, trickle charge, and over/undertemperature conditions. Models in the HEC 66 series cost $55.98 (OEM qty). Total Power International Inc, Lowell, MA. (508) 453-7272.
