○Setting of synchronous function  
BD9221F output frequency with <CLK_IN Freq.*1/2>to N1 and N2 pin.  
(signal amplitude level : H=over 2.4V ,L=under0.8V)  
Set the IC frequency by adjusting RT resistor value, in order to satisfy under synchronous  
condition.  
F(IC)=F(CLK_IN)*1/2*A  
F(IC)・・・IC Freq. F(CLK_IN)・・・Synchronous Freq. A・・・under 90%/over 75%  
However this synchronous function is connected with SRT movement.  
SRT=OFF(OPEN) : synchronous mode.  
SRT=ON(LOW):IC Frequency mode.

NOTE FOR USE  
1. Thisproductisproducedwithstrictqualitycontrol,butmightbedestroyedifusedbeyonditsabsolutemaximumratings.  
Once IC is destroyed, failure mode will be difficult to determine, like short mode or open mode. Therefore, physical  
protectioncountermeasure,likefuseisrecommendedincaseoperatingconditionsgobeyondtheexpectedabsolutemaximum  
ratings.  
2. Thecircuitfunctionalityisguaranteedwithinofambienttemperatureoperationrangeaslongasitiswithinrecommended  
operatingrange. Thestandardelectricalcharacteristicvaluescannotbeguaranteedatothervoltagesintheoperating  
ranges, however the variation will be small.  
3. Mounting failures, such as misdirection or miscounts, may harm the device.  
4. A strong electromagnetic field may cause the IC to malfunction.  
5. The GND pin should be the location within ±0.3V compared with the PGND pin. ALL voltage should be under VCC voltage  
+0.3V  
6. BD9221F incorporate a built-in thermal shutdown circuit (TSD circuit). The thermal shutdown circuit (TSD circuit) is  
designedonlytoshuttheICofftopreventrunawaythermaloperation. ItisnotdesignedtoprotecttheICorguarantee  
its operation of the thermal shutdown circuit is assumed.  
7. When modifying the external circuit components, make sure to leave an adequate margin for external components actual  
value and tolerance as well as dispersion of the IC.  
8. AbouttheexternalFET,theparasiticCapacitormaycausethegatevoltagetochange,whenthedrainvoltageisswitching.  
Make sure to leave adequate margin for this IC variation.  
9. Under operating CP charge (under error mode) analog dimming and burst dimming are not operate.  
10. Under operating Slow Start Control (SS is less than 2.5V), It does not operate Timer Latch.  
11. By STB voltage is changed to 2 states. Therefore, do not input STB pin voltage between one state and the other state  
(0.8~2.0V).  
12. The pin connected a connector need to connect to the resistor for electrical surge destruction.  
13. This IC is a monolithic IC which (as shown is Fig-1) has P+ substrate and between the various pins. A P-N junction is  
formed from this P layer of each pin. For example, the relation between each potential is as follows,  
○(When GND > PinB and GND > PinA, the P-N junction operates as a parasitic diode.)  
○(When PinB > GND > PinA, the P-N junction operates as a parasitic transistor.)  
ParasiticdiodescanoccurinevitablyinthestructureoftheIC.Theoperationofparasiticdiodescanresultinmutual  
interference among circuits as well as operation faults and physical damage. Accordingly you must not use methods by  
whichparasiticdiodesoperate, suchasapplyingavoltagethatislowerthantheGND(Psubstrate)voltagetoaninput
