Figure 9. LED Brightness Control Block Diagram
At first, CH7 operates as pulse frequency modulation (PFM) mode at start-up. After reaching the target output
voltage, CH7 operation is changed from PFM mode to pulse width modulation (PWM) mode automatically. The
output voltage is programmable up to 20 V to use the feedback loop sensed by the external resistances. The
maximum output voltage is calculated by Equation 8. The block diagram is shown in Figure 10.
VOUT7 MAX = 1 + (R2/R1) × 1.25 [V]
(8)
Where:
VOUT7 MAX = Maximum output voltage of CH7 [V]
R1, R2 = Feedback resistance (see Figure 10)
