AiT Semiconductor has introduced the A8160A-030, a step-up DC-DC converter specifically designed for driving white LEDs with a constant current. The internal MOSFET can support up to 10 White LEDs for backlighting and OLED power application, and the internal soft start function can reduce the inrush current. The A8160A-030 uses current mode, a fixed frequency of approximately 1.0 MHz 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 A8160A-030 is available in the SOT-26 package.
