6 / 10 page FAN5610 PRODUCT SPECIFICATION 6 REV. 1.0.2 10/28/03 Digital Control with PWM A is PWM and B is Low. ILED (Average) = δ x 7mA where δ is Duty Cycle. (Note 3) A is High and B is PWM. ILED (Average) = 7mA + δ x 14mA where δ is Duty Cycle. (Note 4, 5) Notes: 3. Proportionally select the duty cycle to achieve a typical LED current between 1mA to 6mA. 4. If either input A or B is high continuously, the other input can be modulated at a maximum rate of 30kHz. If this is not the case, the maximum rate of modulation should be limited to 1kHz. 5. Proportionally select the duty cycle to achieve a typical LED current between 8mA to 20mA. ss A Input (PWM) B Input (0) ss OFF ILED 0mA ILED (Average) = 0.7 x 7mA = 4.9mA ILED (Average) = 0.3 x 7mA = 2.1mA 1KHz 30% Duty Cycle 1KHz 70% Duty Cycle B Input (PWM) ss A Input ss OFF ILED 0mA ILED (Average) = 7mA + 0.7 x 14mA = 16.8mA ILED (Average) = 7mA + 0.3 x 14mA = 11.2mA 1KHz 30% Duty Cycle 1KHz 70% Duty Cycle Digital LED Brightness Control 1. Digital Control A digital to analog converter selects the following modes of operation: OFF, 7mA, 14mA, 21mA per diode. In addition, by turning the "IN B" pin ON and OFF , the current can be modulated between 8 to 20mA to achieve any Iaverage value. 2. Digital Control with PWM Any pin can be modulated by a variable duty cycle ( δ) pulse train. Care should be taken not to use too low frequency, otherwise a flickering effect can be seen.The minimum range is between 100Hz to 5KHz. For a maximum range of LED current, both A and B can be modulated at the same time. A 0101 B 0011 ILED OFF 7mA 14mA 21mA |
