Neubean runs to the white board and writes the following equations.with op amp gain A, and op amp pole ωA.Neubean immediately identifies the important term gm. What is gm? For a MOSFET,Looking at the circuit back in Figure 1, a light bulb goes off in the Neubean’s head. With ...
It can be approximately calculated from the equations: tRCFALL = 0.6 · ROFF · COFF tOFF = tRCFALL + tDT = 0.6 · ROFF · COFF + tDT where ROFF and COFF are the external component values and tDT is the internally generated Dead Time with: 20 kΩ ≤ROFF ≤100 kΩ 0.47 nF ≤...
The frequency of the oscillator can be estimated with the following equations: 4 7 10 I/O 1.72 fOSC = RRT × CCT (1) where fOSC is in Hertz, RRT is in Ohms and CCT is in Farads. Never use a timing resistor less than 5 kΩ. The frequency of the OUTPUT gate drive of the UCx...
Therefore, the converter operates in CCM and the compensation loop requires design based on CCM flyback equations. The current-to-voltage conversion is done externally with the ground-referenced RCS and the internal 2R/R resistor divider which sets up the internal current sense gain, ACS = 3....
