The cxac8516 includes an accurate current mode modulator and a demagnetization detector to ensure the critical current mode, which can make the switch on at the lowest drain voltage

The cxac8516 includes an accurate current mode modulator and a demagnetization detector to ensure the critical current mode, which can make the switch on at the lowest drain voltage (quasi resonant) at any load and input voltage. For cxac8516, the internal 7.5us timer limits its free oscillation frequency to no higher than 120kHz (lower than 150kHz, the frequency starting point of cispr-22 about EMI test). Cxac8516 is an off-line flyback driver chip with low no-load power consumption (< 100 MW), high performance and high cost performance in the range of 100 W
