Error amplifier
The error amplifier compares a sample of the dc-dc converter output voltage to the 0.5V
reference and generates an error signal for the PWM comparator. Output voltage of dc-dc
converter is setting with the resistor divider using the following expression (see fig12):

Oscillator
The oscillator frequency can be set between 20KHz and 500KHz by connecting a resistor and
a capacitor at OSC pin of FP5139 to ground. The oscillator frequency can be determined by
using the graph shown in Figure 9.
The oscillator output is a sawtooth wave with a minimum value of approximately 0.1V and a
maximum value of approximately 0.6V. The PWM comparator compares the oscillator voltage
with error amplifier output voltage; internal DTC voltage (typ. 0.6V) and soft start setting
voltage. When the sawtooth wave voltage is low than above three-output voltage, the output of
FP5139 is high (Turn on NPN transistor or NMOS).
