8 / 13 page  8 www.irf.com IRPLMB1E Fig. 7.4 shows pin VCO and pin VS (HB Voltage) at the shutdown with a shorter time scale. The FMIN pin can be used as trigger as this pin transitions from 5V to COM when the IC enters fault mode or UVLO-. Fig. 7.3: 3 is the voltage in pin VCO and 2 is pin VS Fig. 7.4: 1 is the voltage in pin FMIN, 3 is the voltage in pin VCO, 2 is pin VS 7.3. Low AC line Protection As you can see from figure 7.5, varying the AC line from 220V to 130VAC the ZVMCS circuit of the IR2520 increases automatically the frequency to maintain ZVS. When the mains voltage decreases, the resonant frequency increases, becoming close to the run frequency. This will cause non-ZVS. The IR2520 will detect non-ZVS and increase the frequency continuously as long as non-ZVS is detected. This will protect the half-bridge MOSFETs against hard-switching. |
