SD6864 is current mode PWM+PFM controller with built in high voltage MOSFET used for SWPS, with low standby power and low start current for power switch. In standby mode, the circuit enters burst mode to reduce the standby power dissipation. The switch frequency is 25~67KHz with jitter frequency for low EMI. Builtin peak current compensation circuit makes the limit output power stable even with different input AC voltage. Limit output power can be adjusted through the resistor. Maximum peak current compensation during poweron reduces pressure on transformer to avoid saturation, the peak current compensation will decrease for balance after poweron. [ … ]
