SD6832_Datasheet
CURRENT MODE PWM+PFM CONTROLLER WITH BUILT-IN HIGH VOLTAGE MOSFET
DESCRIPTION
SD6832 is current mode PWM+PFM controller with built-in highvoltage 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.
