SANTA CLARA, Ca. - Power Analog Microelectronics (PAM), a developer of innovative Class-D digital audio amplifiers and high- power LED display driver semiconductors, today announced its first high- voltage 30 watt LED Driver with integrated MOSFET based on the Bipolar-CMOS- DMOS (BCD) Technology developed at Taiwan Semiconductor Manufacturing Corporation (TSMC).

The PAM2842 product announcement is made in conjunction with the 5th China International Forum on Solid State Lighting which is being held today in Shenzhen, China. The PAM2842, with its unique performance and versatility, has just this month won an award in the 2nd National Solid State Lighting Innovation Contest, in China. With a wide input voltage range from 5.5V to 40V, the PAM2842 is a versatile LED Driver that supports Boost, Buck, Buck- Boost, and SEPIC topology. It is capable of driving up to 30 Watts in configurations of 10 x 3W or 30 x 1W LEDs using its own integrated MOSFET. With constant current over wide voltage range and maintaining a 95% efficiency, the PAM2842 guarantees normal operation in spite of input voltage degradation or high temperature environments. Manufactured at TSMC in its advanced 40V BCD technology and with PAM's patent pending proprietary architecture, the PAM2842 also integrates a Power MOSFET. Other features include over current protection, over voltage protection, under voltage lock out, and over temperature protection, which prevents the device (and the LEDs it drives) from sustaining damage. The PAM2842 is housed in a 40-pin QFN (6mm x 6mm) package or TSSOP-20 package. It is ideal for home lighting, automotive lighting, monitor backlighting, and solar-cell lighting applications.

"We are extremely excited about the recognition the PAM2842 has received by the LED Lighting industry, as it has already been used in many LED lighting applications. This innovative high-power LED Driver, with the widest input voltage range, from 5V battery applications to 40V automotive applications, satisfies many stringent lighting requirements", said Johnston Chen, President and chief executive officer of PAM. "In addition, when used as a buck type constant current DC-DC driver to control LEDs for Solar-cell powered lighting, the PAM2842, at 30 watts, delivers the highest power for this expanding energy saving market," continued Chen.

PAM2842 is available in full production.
