RT8206L/M
VOUT2 (Pin 30)
SMPS2 Output Voltage Sense Input. Connect this pin to
the SMPS2 output. VOUT2 is an input to the constant
on-time-PWM one-shot circuit. It also serves as the
SMPS2 feedback input in fixed-voltage mode.
ILIM2 (Pin 31)
SMPS2 Current-Limit Adjustment. The GND − PHASE2
current limit threshold is 1/10th the voltage seen at ILIM2
over a 0.5V to
2.5V
range. There is an internal 5μA current
source from VCC to ILIM2. The logic current limit threshold
is default to 100mV value if ILIM2 is higher than (VCC −
1V).
FB2 (Pin 32)
SMPS2 Feedback Input. Connect FB2 to VCC or GND for
fixed 3.3V operation. Connect FB2 to a resistive voltage-
divider from VOUT2 to GND to adjust output from 2V to
5.5V.
