Taiwan Arthur Wright launched PWM LED driver IC

Taiwan factory Arthur Wright Technology launched AX2002 (2A) / AX2003 (3A) series PWM LED driver IC. AX2002/2003 series is a pulse width modulation output asynchronous DC step-down converter, the use of feedback resistor to control the current of LED, the feedback voltage is only 0.25V, can greatly reduce the power of the feedback resistor. The input voltage range can be from 3.6 volts to a maximum of 23 volts, the output can be connected up to a maximum of 7 LED, very suitable for LCD TV / screen, flashlight, cup lights and other devices.

The AX2002/2003 application provides high conversion efficiency and stable working voltage, the system has complete protection function including flexible start (SS) (SCP), short circuit protection, over temperature protection and overcurrent protection (OCP) function, the switching frequency is fixed at 330KHz or 500Khz.

SOP-8L lead-free package uses standard AX2002/2003 with few external components can be greatly reduced the size of circuit board with heat radiating function can be heat to the printed circuit board, greatly reduce the surface temperature of components to meet customer needs.
