AP3130 Description
The AP3130 is a step-up DC/DC converter specifically designed for driving white LEDs with a constant current. The internal MOSFET can support up to 10X5 White LEDs for backlighting application, and the internal soft start function can reduce the inrush current. The AP3130 uses current mode, fixed frequency of approximately 1.0MHz architecture to regulate the LED current through an external current sense resistor.
