National Semiconductor announced the addition of six high-frequency buck regulators to its  Simple Switcher product family along with a "dial-in" performance enhancement to its Webench design environment. As national Semiconductor stated, the six regulators feature a combination of high pe...

Zetex Semiconductors has introduced three N-Channel enhancement mode MOSFETs, developed specifically for applications with limited drive voltage availability. The 20V ZXMN2B03E6 (SOT236), ZXMN2B14FH and ZXMN2B01F (both SOT23) are capable of low loss switching at a VGS of 1.8V, enabling them to be op...

International Rectifier has launched the IRF6643PbF, a 150V DirectFET MOSFET for isolated DC-DC converters operating from a wide range, 36V to 75V universal telecommunications input and 48V fixed input systems. Combining IR’s advanced DirectFET packaging technology and its HEXFET power MOSFET silico...

Intersil’s ISL6257 is a narrow VDC (voltage direct current) charger controller for Li-Ion/Li-Ion polymer batteries in notebook computers. The true narrow VDC charger controller features narrow VDC output, which allows the system to operate from the regulated charger instead of the adapter. The use o...

Maxim Integrated Products introduces the MAX5092 low-dropout (LDO) regulator with a boost preregulator. The device provides a regulated 3.3V (MAX5092A), 5V (MAX5092B), or adjustable output voltage from a 3.5V to 72V input voltage. This operating-input-voltage range allows for true buck-boost operati...
