PAM developed a built-in MOSFET tube and output 30 Watt High Power LED driver

It is reported that the research and innovation of class D digital audio power amplifier and high power LED display driver chip PAM (Power Analog MicroELectronics) company, today released with built-in 30 watt MOSFET high voltage LED driver, the driver is using TSMC (TSMC) bipolar CMOS-DMOS (BCD) technology and made mass production, now.

It is understood that PAM2842 products are held in Shenzhen, China, the Fifth International Semiconductor Lighting Forum at the same time released. The PAM2842 has a wide input voltage range from 5.5V to 40V, and it is a very flexible LED driver that can work in three operating modes of boost, buck, and boost (SEPIC). It can use its built-in MOSFET to drive 10 or 3 watts of LED, or a 30 watt LED 1. Because of the constant current characteristic and the efficiency of more than 95% in a wide voltage range, the utility model can work normally no matter when the input voltage drops or the environment temperature is very high. Because of the use of TSMC's 40 volt BCD process, and PAM has applied for patents, it also integrates a power MOSFET tube. Other features include over-current protection, over voltage protection, under voltage lockout and over temperature protection, which can prevent permanent damage and protect the LED. PAM2842 is used in 40- pin QFN (6mm x 6mm) package or TSSOP-20 package. The utility model is especially suitable for the application of home lighting, automotive lighting, display backlight and solar illumination.

PAM's president and chief executive officer Chen Jianzhang said: "we are happy to see that the PAM2842 has been used for many LED lighting applications are approved by the LED lighting industry, the innovation of the high power LED driver with wide input voltage from the battery to 5V, car 40V, meet a lot of different lighting applications. Especially when it is used in solar powered constant current DC converter, PAM2842 can give the maximum power of 30W to meet the rapid development of energy-saving market. "
