AP3130 Chipown Small Package, High Performance Asynchronies Boost for 10 WLED Driver General 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. The low feedback voltage of 300mV can minimize power dissipation. Other features include current limit protection, thermal shutdown protection, under-voltage lockout (UVLO), and over-voltage function. The AP3130 is available in space saving SOT-23-6L package.
