External resistor which convert FEAO voltage signal into current
signal for frequency modulation. SR is PWMing Control , when
RSET lower than 1.5V.
Non-inverting input into resonant error amplifier .
Resonant error amplifier output and compensation node for
frequency modulation control.
Inverting input into PWM error amplifier.
Non-inverting input into PWM error amplifier.
PWM error amplifier output and compensation node for PWM
control.
Soft start for FM/PWM operation with 1V enable threshold. Also,
use for auto-restart operation during current limit.
Input to current comparator with 1V threshold.
Oscillator timing components which set the minimum frequency.
Ground
