CH5 is the peak current-mode-controlled nonsynchronous boost converter for CCD+. The switch between
inductor and power GND is integrated into the device and consists of NMOS-FET. Also, this device has a load
switch between the battery and inductor and consists of NMOS-FET. The gate of the switch is controlled by a
charge-pump circuit. The output voltage is programmable up to 18 V to use the feedback loop sensed by the
external resistances. The output voltage is calculated by Equation 5. The block diagram is shown in Figure 6.
VOUT5 = (1 + R2/R1) × 1.0 [V]
(5)
Where:
VOUT5 = Output voltage of CH5 [V]
R1, R2 = Feedback resistance (see Figure 6)
