Description of Blocks

Start-up Circuit
This IC has a built-in start-up circuit. When the AC input voltage is applied, the VH pin is also applied the voltage.
Then the VCC pin voltage is charged by applied current to the VCC pin through the start-up circuit. This charge is
stopped after the VCC pin voltage rises and VCC UVLO is released.
2
AC UVLO (Under Voltage Lockout), X Capacitor Discharge Function
AC UVLO:
At start-up, the voltage occurs at the VH pin when the AC input voltage is applied.
The VCC pin waits the detection of AC input voltage remaining applied voltage and IC switching
is stopped until the VH pin peak voltage becomes more than VINLVP while this IC charges the
VCC pin through the start-up circuit. IC does not work switching operate in AC UVLO operation.
When the VH pin peak voltage is more than VINLVP, AC UVLO function is released and IC works
switching operation.
After stopping AC input voltage supply, the VH pin peak voltage is VINLVP or less for tINLVP
,
IC stops switching operation.
X Capacitor Discharge Function: When the status of the VH pin peak voltage is VINLVP or less continues for tINLVP and
the switching operation is stopped by AC UVLO function, X capacitor discharge
function starts to operate. Since the VH pin detects the voltage change, even if
the VH pin peak voltage is more than VINLVP, If the VH pin does not detect voltage
rising or falling for tINLVP, IC does not work switching operation.

VCC Pin Protection Function
This IC has VCC UVLO and VCC recharge function at the VCC pin.
3.1 VCC UVLO (Under Voltage Lockout)
This is an auto recovery comparator with a voltage hysteresis. When the VCC pin voltage becomes less than
VUVLO2, the IC stops the operation. And, when the VCC pin voltage becomes more than VUVLO1, the operation is
restarted.
3.2 VCC Recharge Function
If the VCC pin voltage drops to less than VCHG1 after once the VCC pin becomes more than VUVLO1 and the IC
starts to operate, the VCC recharge function operates. At this time, the VCC pin is recharged from the VH pin
through the start-up circuit. When the VCC pin voltage becomes more than VCHG2, this recharge is stopped.

4.5.3
Normally, when the MOSFET for switching is turned to ON, surge current is generated at each
capacitor component and drive current and so on. At this time, detection errors may occur in the over
current protection function because the SOURCE pin voltage rises temporary. To prevent these
errors, Leading Edge Blanking function is built-in this IC. This function masks the SOURCE pin
voltage for tLEB from the switch of the Drain pin H to L.
4.6 Minimum ON width function
This IC is built-in minimum ON width function.
4.6.1
Minimum ON width switching function by FB pin pulse count of burst period
Normally, the minimum ON width of this IC is tMIN1. When the operation is burst operation at light load,
IC counts the number of switching from the start of switching after the burst stop is released to the
burst stop again. When switching number is 3 pulses or less IC operates low stand-by mode, and IC
switches minimum ON width. The switching of minimum ON width is decided from tMIN2 to tMIN4 to
correspond to the OFF pin resistor value. As minimum ON width is switched, the number of switching
is low. When it is low standby power mode, if the load is increased, the number of switching increases.
When the number of switching after the burst operation is stopped is 2 pulses or more, the low standby
power mode is switched to the normal mode. Then minimum ON width function is released, minimum
ON width is to tMIN1.

Minimum ON width switching function by OFF pin
Minimum ON width in burst operation is able to switch external resistor at the OFF pin.
IC detects the OFF pin resistor value at the timing of tSTSET2 from VCC UVLO released.

The latch stop operation has a built-in mask timer of tLATCH. It prevents misdetection from noise.
The LATCH pin is pulled up by RLATCH in IC.
The example of using LATCH pin: External Latch stop
The LATCH pin can be operated latch stop by external signal.
As an example, it shows circuit which stops at latch from secondary microcomputer.

Caution 1: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is
operated over the absolute maximum ratings.
Caution 2: Should by any chance the maximum junction temperature rating be exceeded the rise in temperature of the chip may result in deterioration of the
properties of the chip. In case of exceeding this absolute maximum rating, design a PCB with power dissipation taken into consideration by increasing
board size and copper area so as not to exceed the maximum junction temperature rating.
(Note 3) Duty is less than 1 %
(Note 4) When IC mounted singly. Derate by 18.3 mW / °C if the IC is used in the ambient temperature 25 °C or more.
Thermal Dissipation
Make the thermal design so that the IC operates in the following conditions.
(Because the following temperature is guarantee value, it is necessary to consider margin.)
1. The ambient temperature Ta must be 105 °C or less.
2. The IC’s loss must be the power dissipation Pd or less.
The thermal abatement characteristic is as follows.

Operational Notes
1. Reverse Connection of Power Supply
Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when
connecting the power supply, such as mounting an external diode between the power supply and the IC’s power
supply pins.
2. Power Supply Lines
Design the PCB layout pattern to provide low impedance supply lines. Furthermore, connect a capacitor to ground at
all power supply pins. Consider the effect of temperature and aging on the capacitance value when using electrolytic
capacitors.
3. Ground Voltage
Ensure that no pins are at a voltage below that of the ground pin at any time, even during transient condition.
4. Ground Wiring Pattern
When using both small-signal and large-current ground traces, the two ground traces should be routed separately
but connected to a single ground at the reference point of the application board to avoid fluctuations in the
small-signal ground caused by large currents. Also ensure that the ground traces of external components do not
cause variations on the ground voltage. The ground lines must be as short and thick as possible to reduce line
impedance.
5. Recommended Operating Conditions
The function and operation of the IC are guaranteed within the range specified by the recommended operating
conditions. The characteristic values are guaranteed only under the conditions of each item specified by the
electrical characteristics.
6. Inrush Current
When power is first supplied to the IC, it is possible that the internal logic may be unstable and inrush current may
flow instantaneously due to the internal powering sequence and delays, especially if the IC has more than one power
supply. Therefore, give special consideration to power coupling capacitance, power wiring, width of ground wiring,
and routing of connections.
7. Testing on Application Boards
When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may
subject the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power supply
should always be turned off completely before connecting or removing it from the test setup during the inspection
process. To prevent damage from static discharge, ground the IC during assembly and use similar precautions
during transport and storage.
8. Inter-pin Short and Mounting Errors
Ensure that the direction and position are correct when mounting the IC on the PCB. Incorrect mounting may result
in damaging the IC. Avoid nearby pins being shorted to each other especially to ground, power supply and output pin.
Inter-pin shorts could be due to many reasons such as metal particles, water droplets (in very humid environment)
and unintentional solder bridge deposited in between pins during assembly to name a few.
9. Unused Input Pins
Input pins of an IC are often connected to the gate of a MOS transistor. The gate has extremely high impedance and
extremely low capacitance. If left unconnected, the electric field from the outside can easily charge it. The small
charge acquired in this way is enough to produce a significant effect on the conduction through the transistor and
cause unexpected operation of the IC. So unless otherwise specified, unused input pins should be connected to the
power supply or ground line.

10. Regarding the Input Pin of the IC
This IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them isolated. P-N
junctions are formed at the intersection of the P layers with the N layers of other elements, creating a parasitic diode
or transistor. For example (refer to figure below):
When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode.
When GND > Pin B, the P-N junction operates as a parasitic transistor.
Parasitic diodes inevitably occur in the structure of the IC. The operation of parasitic diodes can result in mutual
interference among circuits, operational faults, or physical damage. Therefore, conditions that cause these diodes to
operate, such as applying a voltage lower than the GND voltage to an input pin (and thus to the P substrate) should
be avoided.

11. Ceramic Capacitor
When using a ceramic capacitor, determine a capacitance value considering the change of capacitance with
temperature and the decrease in nominal capacitance due to DC bias and others.
12. Thermal Shutdown Circuit (TSD)
This IC has a built-in thermal shutdown circuit that prevents heat damage to the IC. Normal operation should always
be within the IC’s maximum junction temperature rating. If however the rating is exceeded for a continued period, the
junction temperature (Tj) will rise which will activate the TSD circuit that will turn OFF power output pins. When the Tj
falls below the TSD threshold, the circuits are automatically restored to normal operation.
Note that the TSD circuit operates in a situation that exceeds the absolute maximum ratings and therefore, under no
circumstances, should the TSD circuit be used in a set design or for any purpose other than protecting the IC from
heat damage.
13. Over Current Protection Circuit (OCP)
This IC incorporates an integrated overcurrent protection circuit that is activated when the load is shorted. This
protection circuit is effective in preventing damage due to sudden and unexpected incidents. However, the IC should
not be used in applications characterized by continuous operation or transitioning of the protection circuit.
