where N p and N s are the number of turns for primary side and reference output, respectively, V o is the output voltage, V F is the diode (D R ) forward voltage drop and V sense
A by-product of BCM is that the boost converter runs with variable switching frequency that depends primarily on the selected output voltage, the instantaneous value of the input
A side effect of BCM is that the boost converter runs with variable switching frequency that depends primarily on the selected output voltage, the
During the turn-off transient, boost inductor current changes the path from MOSFET to output diode and before the output diode turns on; a minor voltage peak can be shown at
ON Semiconductor products are not designed, intended, or authorized for use as a critical component in life support systems or any FDA Class 3 medical devices or medical devices with
In addition, a complete list of all device types supplied from this process is included to aid in cross reference searches and the selection of preferred device
The output voltage is indirectly sensed by sampling the transformer winding voltage (V SH ) around the end of diode current discharge time, as illustrated in Figure 4..
Should Buyer purchase or use ON Semiconductor products for any such unintended or unauthorized application, Buyer shall indemnify and hold ON Semiconductor and its officers,
