Sipex Corp. (Billerica, MA) announced the availability of its new SP6639/40/53 family of low-voltage dc/dc buck regulators. These devices have 1 ohm on-chip power MOSFETs and can deliver up to 100mA at either fixed (SP6639, 5.0V; SP6640, 3.3V; SP6653, 3.0V) or user-adjustable output voltages. Sipex claims that its new buck regulators can sustain up to […]
ON Semiconductor LLC (Phoenix, AZ) unveiled a new Pulse Width Modulator (PWM) current-mode controller for low-power universal off-line power supplies. The NCP1200, an off-line controller, allows for implementation of 42V to 500V off-line power supplies with minimal external components. It is suitable for applications in which low part count and low power are critical. The […]
Siliconix Inc. (Santa Clara, CA) announced a series of new TrenchFETs. Housed in Little Foot SC-89 and SC-75 packages, the new devices serve as a replacement for the digital bipolar transistors used for simple or light-load switching in portable communications systems, computer motherboards, power supply converter circuits and battery-operated equipment. Devices in the three-pin Little […]
Tyco Electronics Corp. (Menlo Park, CA) announced that its Raychem circuit protection division has completed the qualification process for the UL Total Certification Program.
