SD6834 PWM PFM Power Management IC
- SD6834 is current mode PWM+PFM controller with built-in high-voltage MOSFET used for SMPS.
- 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 compensation circuit makes the limit peak current stable even with different input AC voltage.
- Maximum peak current compensation during power-on reduces pressure on transformer to avoid saturation, the peak current compensation will decrease for balance after power-on.
- Limit output current can be adjusted through the resistor connected to CS
