Species association increases biofilm resistance to chemical and mechanical treatments. Water Res. 2009;43:229-237. [Cited in This Article: 1] 161. Kara D, Luppens SB, Cate JM. Differences between single- and dual-species biofilms of Streptococcus mutans and Veillonella parvula in growth, ...
The pulse feedback approach increases the operating ffrequency by up to 50%. Figure 28, Oscillator Frequency vs. Timing Capacitor with Pulse Feedback, shows the impact to the oscillator frequency at buck converter for Vin = 12 V and Vout = 3.3 V with pulse feedback resistor R7 = 10 kW....
For light loads (less than approximately 300 mA) it may be desirable to operate the regulator in the discontinuous mode, because the inductor value and size can be kept relatively low. Consequently, the percentage of inductor peak−to−peak current increases. This discontinuous mode of ...
A reduction of the maximum duty cycle may be required for specific converter configurations. This can be accomplished with the addition of an external deadtime resistor (RDT) placed across CT. The resistor increases the discharge current which reduces the on−time of the output switch. The ...
Consequently, the percentage of inductor peak−to−peak current increases. This discontinuous mode of operation is perfectly acceptable for this type of switching converter. Any buck regulator will be forced to enter discontinuous mode if the load current is light enough. 0.4 A Inductor Current ...
