Custom-specific solutions (ASICs) and production of mixed-signal ICs are the main focus of PREMA Semiconductor GmbH. 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 site http://www.prema.com/Application/pr4404_e.html. 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. All data sheets are listed at http://www.prema.com/Application/applications.html.
