High Power LED Driver Features n n n n n n n n n n n n PAM2842 Description The PAM2842 is a high power LED driver, capable of driving up to 10 high power LEDs in series. The PAM2842 supports buck, boost and sepic topology. The PAM2842 Features over current protection , over voltage protection , under voltage lockout and over temperature protection, which prevent the device from damage. LED dimming can be done by using a PWM signal to the P pin. The PAM2842 is available in 40-Pin QFN6x6 and TSSOP-20 packages. Output Power up to 30W Chip Enable with Soft-start Analog and PWM Dimming Peak Efficiency up to 97% Low Quiescent Current Switching Frequency Adjustable Support Buck/Boost/Sepic Topology Over Current Protection Over Voltage Protection Thermal Protection UVLO Tiny Pb-Free Packages : 40-Pin QFN6x6 and TSSOP-20 Applications n Home Lighting n Automotive Lighting n Monitor Backlighting Typical Application Circuit Boost with Low Side Current Sense Vin 1μF L1 Boost with High Side Current Sense Vin L1 33 μ H 1μF 0.14Ω 33 μ H PGND SW SW OV VDD-5V 1μF 1k Ω 10nF 10 μ F 0.14Ω 1μF 130kΩ 430kΩ PGND PGND HVIN 15kΩ SW SW OV VDD-5V 1μF 430kΩ ..
