2兆赫, 4 Channel100毫安WLED / RGB驱动器

These parts are in production but have been determined to be NOT FOR NEW DESIGN. This classification indicates that sale of this device is currently restricted to existing customer applications. The device should not be purchased for new design applications because obsolescence in the near future is \n• 600 kHz to 2.2 MHz switching frequency—ability to operate above the AM band \n• Internal bias supply for single-supply operation (VIN = 8 to 21 V) \n• Boost converter with integrated 40 V DMOS switch and OVP—load-dump protection \n• 3.5 µA shutdown current—limits battery drain \n• Active current;

A8502

宽输入电压范围,高效率

The A8502 is a multi-output white LED driver for small-size LCD backlighting. It integrates a current-mode boost converter with internal power switch and two current sinks. The boost converter can drive up to 24 LEDs, 12 LEDs per string, at 120 mA. The LED sinks can be paralleled together to achieve \n• Wide input voltage range of 5 to 40 V for start/stop, cold crank and load dump requirements\n• Sync function to synchronize boost converter switching frequency up to 2.3 MHz, allowing operation above the AM band\n• Single resistor primary OVP minimizes VOUT leakage\n• LED current of 120 mA per c;

A8503

高效6通道, 2兆赫, WLED / RGB驱动器

The A8503 is a multi-output WLED/RGB LED driver for medium-size LCD backlighting. It integrates a current-mode boost converter with internal power switch and six current sinks. The boost converter can provide output voltages up to 47 V. The boost converter can drive up to 72 LEDs at 20 mA per LED wi \n• Active current sharing between LED strings for ±0.6% accuracy and matching \n• Drives up to 12 series × 6 parallel = 72 LEDs (Vf = 3.2 V, If = 20 mA) at 5 V \n• Each individual current sink is capable of 32 mA \n• Adjustable overvoltage protection (OVP) \n• 600 kHz to 2 MHz adjustable switch;
