electronica 2008 - PREMA - 1V Boost Driver for Power LEDs

24th September 2008

Custom-specific solutions (ASICs) and production of mixed-signal ICs are the main focus of PREMA Semiconductor GmbH at electronica. Their product range is growing continuously, particularly by buck and boost LED drivers.
/> The new PR4404 is a LED driver providing more than 150mA out of one battery cell and up to 300mA from two batteries for one to three power LEDs. A hold input allows controlling the LED brightness via a PWM signal or switching the LED from a microcontroller.

You need only a few components to realize applications like flash lights, blinking lights or LCD backlighting in a cost-efficient way with small board sizes.

Several applications and circuits can be found in the comprehensive data sheet on the web sitel. Samples of the PR4404 are available upon request.

PREMA will announce further standard ICs this year such as additional DC-DC converters and high voltage operational amplifiers for voltages of up to 80V.

PREMA´s application team is looking forward to meeting interested visitors at the booth on the fair grounds in Munich to discuss ASIC requirements and the new standard ICs at this year's electronica 2008.
