FREQ (Frequency Setting)
This pin allows the setting of the operating switching
frequency by connecting a resistor to ground. The
frequency range is from 50kHz to 250kHz.
VSENSE (Voltage Sense/Feedback)
The output bus voltage is sensed at this pin via a
resistive divider. The reference voltage for this pin is
3V.
VCOMP (Voltage Loop Compensation)
This pin provides the compensation of the output
voltage loop with a compensation network to ground
(see Figure 2). This also gives the soft start function
which controls an increasing AC input current during
start-up.
VCC (Power Supply)
The VCC pin is the positive supply of the IC and should
be connected to an external auxiliary supply. The

3.4.1
Soft Over Current Control (SOC)
The IC is designed not to support any output power
that corresponds to a voltage lower than -0.75V at the
ISENSE pin. A further increase in the inductor current,
which results in a lower ISENSE voltage, will activate
the Soft Over Current Control (SOC). This is a soft
control as it does not directly switch off the gate drive.
It acts on the nonlinear gain block to result in a reduced
PWM duty cycle.

the IC will be shutdown. It is implemented using
comparator C3 with a threshold of 0.6V as shown in the
IC block diagram in Figure 2.
3.4.4
Over-Voltage Protection (OVP)
Whenever VOUT exceeds the rated value by 5%, the
over-voltage protection OVP is active as shown in
Figure 6. This is implemented by sensing the voltage at
pin VSENSE with respect to a reference voltage of
3.15V. A VSENSE voltage higher than 3.15V will
immediately reduce the output duty cycle, bypassing
the normal voltage loop control. This results in a lower
