SD6835
DESCRIPTION
SD6835 is current mode PWM+PFM controller used for SMPS with built-in high-voltage MOSFET and external sense resistor.
It features low standby power and low start current. In standby mode, the circuit enters burst mode to reduce the standby power dissipation.
The switch frequency is 25~67KHz decided by the load with jitter frequency for low EMI.
Built-in peak current pensation circuit makes the limit peak current stable even with different input AC voltage. Built-in limit output power pensation circuit to balance the limit output power under different AC voltage inputs. Built-in slope pensation circuit to adapt to more transformer applications. Maximum peak current pensation during power-on reduces pressure on transformer to avoid saturation, the peak current pensation will decrease for balance after power-on. Limit output current can be APPLICATIONS adjusted through the resistor connected to CS. It integrates various protections such as undervoltage...
