Features
Description
„ Current Mode PWM Control with a Fixed Operating Frequency (300kHz)
The FS6X-Series is specially designed for off-line DC-DC converters with minimal external components. This device combines a current mode PWM controller with a high voltage power
SenseFET in a single package. The PWM controller includes
integrated fixed frequency oscillator, line under voltage lockout,
sleep on/off function, thermal shutdown protection, over voltage
protection, pulse-by-pulse current limit, and temperature compensated precise current sources for a loop compensation.
Compared with the discrete MOSFET and PWM controller solution, the FS6X-Series can reduce total cost, component count,
size, and weight, while simultaneously increasing efficiency,
productivity, and system reliability.

This pin is internally connected to the inverting input of the PWM comparator. The collector of an opto-coupler is typically tied to this pin. For stable operation, a capacitor should
be placed between this pin and GND. If the voltage of this pin reaches 7.5V, the over load

Pin Function Description
This pin is not connected.
According to the voltage of this pin, three operation modes are defined: normal operation
mode, line under voltage lock out mode, and sleep mode. If the voltage of this pin is
smaller than 2.55V, the IC goes into the line under voltage lock out, stopping switching
operation. If the voltage of this pin is smaller than 1.8V, the IC enters into sleep mode.
During sleep mode, reference voltage generation circuit including the shunt regulator is
disabled and only 300uA operation current is required.

Typical Performance Characteristics (Continued)
1. Startup
3. Protection Circuit
To guarantee stable operation of the control IC, Vcc has under
voltage lockout (UVLO) with 6V hysteresis. Figure 16 shows the
relation between the supply current (Icc) and the supply voltage
(Vcc). Before Vcc reaches 15V, the start-up current is 60μA,
which is usually provided by the DC link through start-up resistor. When Vcc reaches 15V, the control IC begins operation and
the operating current increases to 10mA as shown. Once the
control IC starts operation, it continues its normal operation
unless Vcc goes below the stop voltage of 9V.
Besides pulse-by-pulse current limit, the FS6X-Series has the
following self protection functions: over load protection (OLP),
over voltage protection (OVP), and thermal shutdown (TSD).
Because these protection circuits are fully integrated into the IC
without external components, the reliability is improved. In the
event of a fault condition, FS6X-Series enters into auto-restart
operation. Once the fault condition occurs, switching operation
is terminated, and the MOSFET remains off, which causes Vcc
to be reduced. When Vcc reaches 9V, the protection is reset
and the supply current reduces to 60uA. Then, Vcc begin to
increase with the current provided through the start-up resistor.
When Vcc reaches 15V, FS6X-Series resumes its normal operation if the fault condition is removed. In this manner, the autorestart alternately enables and disables the switching of the
power MOSFET until the fault condition is eliminated as illustrated in Figure 18.

2. Feedback Control
The FS6X-Series employs current mode control. The voltage of
the feedback pin is compared with the current sense voltage for
pulse width modulation (PWM). Figure 17 illustrates the simplified PWM block. The feedback voltage determines the peak
drain current of the SenseFET. Usually, an opto-coupler, along
with the TL431(shunt regulator) are used to implement the feedback network. The collector of the opto-coupler transistor is
connected to the feedback pin and the emitter is connected to
the ground pin. When the voltage of the reference pin of the
TL431 exceeds the internal reference voltage of 2.5V, the optocoupler diode current increases, pulling down the feedback voltage.

3.1 Pulse-by-pulse Current Limit
431
VSD
As shown in Figure 17, the drain current of the power MOSFET
is limited by the inverting input of PWM comparator (Vfb*).
Assuming that the 0.9mA current source flows only through the
internal resistor (28R +R= 2.9k), the cathode voltage of diode
D2 is about 2.6V. Since D1 is blocked when the feedback voltage (Vfb) exceeds 2.6V, the maximum voltage of the cathode of
D2 is 2.6V. Therefore, the maximum value of Vfb* is about 0.1V,
which limits the peak value of the power MOSFET drain current.

Applications Information
switching. To avoid undesired activation of OVP during normal
operation, Vcc should be properly designed to be below 25V.
Overload means that the load current exceeds a pre-set level
due to an abnormal situation. In this situation, the protection circuit should be activated to protect the SMPS (Switch Mode
Power Supplies). However, even when the SMPS is in normal
operation, the over load protection circuit can be activated during the load transition. To avoid this undesired operation, the
over load protection circuit is designed to be activated after a
specified period to determine whether it is a transient situation
or an overload situation. Because of the pulse-by-pulse current
limit capability, the maximum peak current through the SMPS is
limited, and therefore the maximum input power is restricted
with a given input voltage. If the output consumes beyond this
maximum power, the output voltage (Vo) decreases below the
set voltage. This reduces the current through the opto-coupler
diode which also reduces opto-coupler transistor current
increasing Vfb. If Vfb exceeds 2.6V, D1 is blocked and the 5mA
current source starts to charge Cfb slowly compared to when
the 0.9mA current source charges Cfb. In this condition, Vfb
continues increasing until it reaches 7.5V, and the switching
operation is terminated at that time as shown in Figure 19. The
delay time for shutdown is the time required to charge Cfb from
2.6V to 7.5V with 5mA. When Cfb is 10nF (103), T12 is approximately 9.8ms and when Cfb is 0.1mF (104), T12 is approximately 98ms. These values are enough to prevent SMPS from
being shut down during transient situations.
3.4 Thermal Shutdown (TSD)
The thermal shutdown circuitry senses the junction temperature. The threshold is set at 160×C. When the junction temperature rises above this threshold (160×C), the power MOSFET is
disabled.
4. Line UVLO and Sleep Mode
According to the voltage of the Line Sense pin, three operation
modes are defined: normal operation mode, line under voltage
lock out mode, and sleep mode, as shown in Figure 20. When
the voltage of this pin is over 2.55V, FS6X-Series operates in
normal mode. When the voltage of this pin is less than 2.55V, it
goes into line under voltage lock out mode terminating switching
operation. When the voltage of this pin is less than 1.8V, it
enters into sleep mode. During sleep mode, the reference voltage generation circuit, including the shunt regulator, is disabled
and only 300mA operation current is required.

3.3 Over Voltage Protection (OVP)
In the case of a malfunction in the secondary side feedback circuit, or feedback loop open caused by a defect of solder, the
current through the opto-coupler transistor becomes almost
zero. Then, Vfb climbs up in a similar manner to the over load
situation, forcing the preset maximum current to be supplied to
the secondary side until the over load protection is activated.
Because more than required energy is provided to the output,
the output voltage may exceed the rated voltage before the over
load protection is activated, resulting in the breakdown of the
devices in the secondary side. To prevent this situation, an over
voltage protection (OVP) circuit is employed. In general, Vcc is
proportional to the output voltage and FS6X-Series uses Vcc
instead of directly monitoring the output voltage. If VCC
exceeds 25V, OVP circuit is activated resulting in termination of
