The Output Driver's current is 60mA, and permit to drive white LEDs of Max. 12 pcs (4 series, 3 parallel). The PWM Luminance Control's registers are 8 which are selected in 64 levels, and the LEDs Luminance is automatically adjusted by A/D Converter and the external illuminance sensor. In addition, the Step-Up DC/DC Converter's frequency become high by the external capacitor, and it permit the use of small, low-profile inductors and capacitors to minimize the footprint in space-conscious portable applications. NJU6052 is suitable for PDA, Camcorder, Car Navigation, LCD TV and so on. |
