Catalyst Semiconductor has announced a 2W LED driver to address high-power backlighting applications. The CAT4240 boost converter provides a high switch current up to 750mA and high voltage up to 38V, making it ideal for driving a wide range of backlighting applications ranging from 1W LEDs in series to multiple strings of lower-power LEDs.

Catalyst Semiconductor has added to its range of voltage supervisors with four new devices that give designers industry-standard performance for monitoring the power supply (Vcc) status of a microprocessor, microcontroller, ASIC or other system processor.

Catalyst Semiconductor has launched the first device in its new line of low dropout (LDO) regulators. The CAT6219 LDO regulator is one of only a few devices available that provides a 500mA peak output current in a tiny, five-lead, 1mm profile thin SOT-23 package.

Catalyst Semiconductor has announced the CAT4004, a new four-channel LDD (low dropout driver) designed for emerging, power-conscious portables where the LEDs are driven directly from the battery. With the migration of white LEDs to lower forward voltages, a number of portable applications are now able to drive LEDs directly from the system battery without the need to boost voltage. The new CAT4004 is designed specifically to meet the needs of t...

Catalyst Semiconductor has added a new 32-tap device to its family of over 35 Digitally Programmable Potentiometers (DPP). The CAT5126 offers one-time wiper programmability via a simple two-wire serial interface, which enables system designers to set the wiper’s value after power-on and also disable the interface to prevent further adjustments. The device also offers the flexibility of not disabling the interface, in which case the system wil...

Catalyst Semiconductor, Inc. has introduced its CAT3643 three-channel and CAT3644 four-channel Quad-Mode charge pumps. The CAT3643 Quad-Mode charge pump is said to be the world’s smallest, highest efficiency charge pump, delivering 10 percent higher efficiency compared to three-mode charge pumps, in a 2.5mm x 2.5mm XQFN package with a 0.4mm profile. The CAT3643 drives up to three LEDs and comes just two months after Catalyst’s launch of its...

Catalyst Semiconductor has launched three new families of voltage supervisors with the industry’s broadest selection of embedded memory. The CAT130xx supervisor family offers 1-, 4-, 8- and 16-kbit embedded EEPROM with Microwire serial interface. The CAT140xx and CAT150xx provide 2-, 4-, 8- and 16-kbit embedded EEPROM with I2C and SPI serial interface protocols, respectively.

Catalyst Semiconductor has added five new 32-tap devices to its extensive family of over 30 Digitally Programmable Potentiometers [DPP(tm)]. The CAT5123, CAT5124 and CAT5125 are volatile devices, while the CAT5127 and CAT5129 offer non-volatile wiper storage. All of the new Catalyst digital potentiometers feature a user-friendly up/down control interface.
