■ Description of each circuit
13 REF
1. Oscillator section
This section outputs sawtooth waves oscillating between 0.15
and 3.55V using the capacitor charge and discharge
characteristics. Figure 1 shows how to connect the required
external components to this circuit. The oscillation frequency
is determined by the CT and RT values. The relationship
between the CT and RT values is shown in characteristic
curves. Pin 14 (SYNC) is a synchronizing input terminal
whose threshold voltage is about 1V. As Fig. 1 shows, input
rectangular synchronizing signal waves to pin 14 through an
RC circuit. Set the free-running frequency about 10% lower
than the synchronizing signal frequency. Connect a clamp
diode (D1) to prevent an unwanted current inside the IC.

this circuit.

active filter does not operate stably. To ensure stable
operation, set the fc value to about 1Hz.
An overvoltage detection comparator (C1) is built in to limit the
voltage if the output voltage exceeds the design value. The
reference input voltage (Vp) is as follows:
Vp = α • Vr ............................................................. (4)

The connections shown in Fig. 2 limit the output voltage to α
times the design value.

3. Current error amplifier and overcurrent limiting circuit
The current error amplifier forms a current loop to change the
input circuit current into sinusoidal waves. As Fig. 3 shows, the
multiplier output is connected to pin 2 (IIN –) through a resistor
(RA) to input the reference current signal. Pin 16 (IDET) is a
current input terminal. Design the circuit so that the voltage at
pin 16 will be within the range from 0 (GND potential) to –1.0V.
Connect a phase correction resistor and capacitors across pin
1 (amplifier output) and pin 2. See Fig. 4 for the expected gain
characteristics of the circuit shown in Fig. 3.

overcurrent. The threshold voltage for overcurrent detection at
pin 16 is –1.15V for FA5331 and –1.10V for FA5332. Connect
noise filters Rn and Cn to prevent the voltage at pin 16 from
fluctuating due to noise, causing the comparator to malfunction.
For Rn, select a resistor of up to 100Ω for FA5331 and up to
27Ω for FA5332. (See P64, 4. No-load operation )

4. Comparator for PWM
Figure 5 shows the comparator for PWM. When the oscillator
output (Va) is smaller than the current error amplifier output
(Vc), the comparator output is high and the output ON signal is
generated at pin 8. Pin 11 (CS) is a terminal for soft start. This
terminal charges capacitor C4 with the internal constant current
(10µA) for a soft start. Priority is given to Vb and Vc whichever
is lower.

The multiplier generates a reference current signal. Input a
fully rectified sinusoidal signal voltage into pin 3 (VDET).
Design the circuit to keep the peak voltage at pin 3 within a
range from 0.65V to 2V for FA5331 and 0.65V to 2.4V for
FA5332. The multiplier output voltage (Vm) is roughly given as

Figure 7 shows the ON/OFF control input circuit. If pin 12 is set
to the high level (enable), this IC outputs pulses from the OUT
pin. If pin 12 is set to the low level (disable), the internal bias
power (reference voltage) goes off and the IC current
consumption becomes about 1/10 that of its ON state. The
output level of pin 11 (CS for soft start) also goes low.

As Fig. 8 shows, pin 9 is configured as the high power terminal
(VC), independent of the IC power terminal (VCC). This pin
allows an independent drive resistance when the power
MOSFET is ON and OFF. If the drive resistances in the ON and
OFF states are Rg (on) and Rg (off), the following formulas can
be used to determine the total gate resistance
Rg:

In the standby state, the output level of pin 8 is held low.
If the potential at the drain terminal of the power MOSFET
fluctuates, the gate-drain capacitance may drive the IC output
voltage at pin 8 to below 0. Once the voltage at pin 8 reaches
–0.6V, an unwanted current flows in the IC and a large abnormal
current flows in the output circuit when the output transistor is
turned on. To prevent this, connect a Schottky diode across the
gate and source of the power MOSFET.

■ Design advice
1. Start circuit
DB1
Figure 9 shows a sample start circuit. Since the IC current
while the Vcc pin voltage rises from 0V to VTHON is as small as
90µA (typ.), the power loss in resistor RA is small. If an
additional winding is prepared in the voltage step-up inductor
(L), power to the control circuit can be supplied from this
circuit. However, the voltage must be stabilized by a regulator
circuit (REG) to prevent an excess rise of the IC supply voltage
(Vcc). Use fast or ultra-fast rectifier diodes for the rectifier circuit
(DB1) of the winding for high-frequency operation.

2. Current sensing resistor
The current sensing resistor (Rs) detects the current in the
inductor. Rs is used to make the input current sinusoidal. The
current in the inductor produces a negative voltage across Rs.
The voltage is input to IC pin 16 (IDET). Determine the value
of Rs so that the peak voltage of the IDET pin is –1V.

Example: FA5332
When Vin is 85V and Pin is 300W, the formulas of (11)
and (12) can be calculated as:
Vin: Minimum AC input voltage (effective value) [V]
Pin: Maximum input power [W]
Since the threshold voltage of the overcurrent limiting circuit
(pin 16) is –1.15V for FA5311 for and –1.10V for FA5332, the
peak input current limit (ip) is determined by:

3. Voltage step-up type converter
Figure 9 shows the basic circuit of a voltage step-up type
converter which is used as a power factor correction.
If R6 is set to 2.7kΩ to satisfy these formulas, R7 becomes
480kΩ.
(a) Output voltage
Example:
For stable operation, set the output voltage to be 10V or more
over the peak value of the maximum input voltage. When
using this IC for an active filter, set the output voltage (Vo) as
follows:
When Vin is 85V, Vo is 385V, and γ is 0.2, the formula of (14)
can be calculated as:

Vo ≥ √ 2 • Vin + 10V
Vin: Maximum AC input voltage [V]
(effective value of sinusoidal wave)
(c) Smoothing capacitor
When a voltage step-up converter is used in a power factor
(b) Voltage step-up inductor
correction circuit, the input current waveform is regulated to be
in-phase with the input voltage waveform. Therefore, ripple
noise of twice the input line frequency appears at the output.
The output voltage (υo) is represented as:
When using a voltage step-up converter in continuous current
mode, the ratio of inductor current ripple to the input peak
current is set to about 20%. Determine the inductance as
follows:
Vin2 ( Vo – √ 2 • Vin )

Vin: Minimum AC input voltage (effective value) [V]
γ : Ratio of inductor current ripple (peak to peak value) to the
input peak current (about 0.2)
fs: Switching frequency [Hz]
Pin: Converter’s maximum input power [W]
Vo:Average output voltage
Io: Output current
ωo: 2π fo (fo: Input power frequency, 50 or 60Hz)
C: Smoothing capacitor value
Therefore, the peak-to-peak value of the output ripple voltage
Vrp is given by:
As the characteristic curves on page 66 show, the peak
voltage at pin 3 should be at least 0.65V, even when the AC
input voltage is minimal. Considering this, determine R6 and
R7 shown in Fig. 6.

•You must not connect RX which reduces DC gain of current
error amplifier.
•You can connect R5 which is series with capacitor C3.

For FA5332 (Fig.11)
Rn ≤ 27Ω
and, RX: don’t connect.

ROFST
•You can connect R5 which is series with capacitor C3.
•If you connect ROFST, dead time of AC input current will
extend.

5. How to prevent from intermittent switching of low
frequency
An intermittent switching, which frequency is lower than 10Hz,
occurs in some applications.

Current
detection

IDET
In this case, it is possible to prevent from this intermittent
switching to reduce feedback gain by decreasing the
resistance of R4. (See Fig. 2)
Cn
You must check the effect thoroughly because this intermittent
switching depends on load, temperature and input condition.
