APW7128

APW7128 30V, 1.2MHz, White LED Driver Features General Description Wide Input Voltage Range from 2.7V to 21V High Current-Limit up to 3.5A 0.5V Reference Voltage with ± 3% System Accuracy 50mΩ Integrated N-FET Fixed 1.2MHz Switching Frequency High Efficiency up to 95% Open-LED Protection Under-Voltage Lockout Protection ALS Control Input Pin Over-Temperature Protection Low Shutdown Current: <1µA 3mmx3mm DFN-10 Package Lead Free and Green Devices Available (RoHS Compliant) The APW7128 is the high power and high efficiency boost converter with an integrated 30V FET ideal for LCD panel backlighting applications. 30V output voltage allows for 8 high-power LEDs in series, and 3.5A inductor current limit allows for more LED strings connected in parallel. The low 0.5V feedback voltage offers higher efficiency in WLED driver applications. The wide input range from 2.7V to 21V made APW7128 a perfect solution for various applications such as LCD monitor and portable devices. The OVP pin monitors the output voltage to protect IC during open load and FB pin short circuit operations. The APW7128 provides the ALS pin to simplify the interface to an ambient light sensor for automatic dimming. The APW7128 is available in the thermally enhanced DFN-10 lead 3mmx3mm package.
