Digital pot is simple alternative

Housed in a small, SOT-23, 8-lead package, the new CAT5128 digital potentiometer is ideal for a wide range of control and calibration applications.

News from Catalyst Semiconductor ( 3 April 2008)

Fractional charge pump boosts LED drive efficiency

The CAT3637 is optimised for applications with one bank of five or six identical LED channels, a typical configuration for larger LED screen portable products.

News from Catalyst Semiconductor (14 March 2008)

Supervisors monitor processor power

Voltage supervisors give designers industry-standard performance for monitoring the power supply status of a microprocessor, microcontroller, ASIC or other system processor.

News from Catalyst Semiconductor ( 4 February 2008)

LED driver runs displays at low voltages

Eight-channel constant-current sink LED driver is designed for billboard, marquee, instrument and other large general-purpose LED displays.

News from Catalyst Semiconductor (17 January 2008)

LED driver gains a fractional advantage

Fourth mode of operation at 1.33x delivers higher average efficiency, without the need for the additional capacitor required by all existing four-mode charge pumps.

News from Catalyst Semiconductor (18 December 2007)

LED driver suits medium-size LCDs

A high-voltage CMOS output stage in the device allows five LED strings to be accurately biased and regulated from a low voltage input supply while still delivering efficiency levels of up to 87%.

News from Catalyst Semiconductor (14 November 2007)

LED driver provides precision control

Device drives 16 LEDs directly in parallel and provides LED dimming in 256 brightness steps for backlighting and RGB colour mixing.

News from Catalyst Semiconductor (31 October 2007)

Two regulators in one save space and cost

Each LDO in the CAT6221 has an independent enable pin and, combined, offer low quiescent current, 1% initial accuracy, and a very low typical dropout voltage.

Driver powers up large LED displays

Constant-current sink LED driver is designed for billboard, marquee, instrument and other larger, general-purpose LED displays.

News from Catalyst Semiconductor ( 4 October 2007)

Digital pots come in smaller packages

Digitally programmable potentiometer now available in an 8-lead 2 x 2.5mm TDFN package, making it the world's smallest nonvolatile digital potentiometer.

News from Catalyst Semiconductor (16 August 2007)

Convertor is cooler choice for LED driving

Buck convertor offers a simpler and smaller alternative to linear regulators for driving high-brightness LEDs in step-down applications, eliminating the need for heatsinks.

News from Catalyst Semiconductor (26 July 2007)

LDOs are power-saving alternatives

Catalyst's LDO products are designed with a "quick start" feature to ensure a fast turn-on time of less than 150us, further optimising the devices for low-power applications.

News from Catalyst Semiconductor (28 June 2007)

Boost convertor powers big backlights

LED driver addresses high-power backlighting applications from 1W LEDs in series to multiple strings of lower-power LEDs.

News from Catalyst Semiconductor ( 7 June 2007)
