Power Analog Micro Announces 30W LED Driver With Integrated MOSFET

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

The PAM2842 has a wide input voltage range from 5.5 to 40V. The device is a versatile LED Driver that supports boost, buck, buck- boost, and SEPIC topology. It is capable of driving up to 30W 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 is said to guarantee 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 (6 x 6mm) package or TSSOP-20 package. It is suitable 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 CEO 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."
