Note 3: Low duty cycle pulse technique are used during test to maintain junction temperature as close to ambient temperature  
as possible.  
Note 4: If the output switch is driven into hard saturation (non-Darlington configuration) at low switch currents (≤ 300mA) and  
high driver currents (≥ 30mA), it may take up to 2.0us for it to come out of saturation. This condition will shorten the off time  
at frequencies 30KHz, and is magnified at high temperatures. This condition does not occur with a Darlington configuration,  
since the output switch cannot saturate. If a non-Darlington configuration is used, the following output drive condition is rec-  
ommended:

Figure 10. Step-Up Converter (Note 5)  
Note 5: This is a typical step-up converter configuration. In the steady state, if the resistor divider voltage at pin  
5 is greater than the voltage in the non-inverting input, which is 1.25V determined by the internal reference, the  
output of the comparator will go low. At the next swithching period, the output switch will not conduct and the  
output voltage will eventually drop below its nominal voltage until the divider voltage at pin 5 is lower than 1.25V.  
Then the output of the comparator will go high, the output switch will be allowed to conduct. Since VPIN5=VOUT  
*
R2/(R1+R2)=1.25(V), the output voltage can be decided by VOUT=1.25 * (R1+R2)/R2 (V).

Figure 12. Voltage Inverting Converter (Note 7)  
Note 7: This is a typical inverting converter configuration. The working process in the steady state is similar to  
step-up converter, the difference in this situation is that the voltage at the non-inverting pin of the comparator is  
equal to 1.25V+VOUT, then VPIN5=VOUT*R2/(R1+R2)=1.25V+VOUT, so the output voltage can be decided by  
VOUT=-1.25*(R1+R2)/R1 (V).
