CH7 is the voltage-mode-controlled nonsynchronous boost converter for the backlight LED. The switch between
the inductor and power GND is integrated into the device and consists of NMOS-FET. Also, this device has a
load switch to control the output current and consists of NMOS-FET. The output current is constant and is
calculated by Equation 7. It is controlled by the B_ADJ (pin 32) input voltage as shown in Figure 8. The B_ADJ
input voltage is required as an analog input. When it is required to input PWM signal for B_ADJ, the RC filter is
needed.
Where:
ILED = Output current of CH7 [A]
RSENSE = Sense resistor between FBC and PGND5/7 []
VBADJ = B_ADJ input voltage (0 < VBADJ < 1) [V]
Figure 8. Output Current vs B_ADJ Input Voltage (RSENSE = 10
)
The principle of the operation is to adjust the duty cycle of the MOSFET. When the B_ADJ input voltage is
changed, the level of “A” point shown in Figure 9 is changed to get the desired duty cycle compared to the sense
current.
