SD686X
CURRENT MODE PWM+PFM CONTROLLER WITH BUILT-IN HIGH VOLTAGE
MOSFET
DESCRIPTION
SD686X 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.
Built-in 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 power-on reduces pressure on transformer to
DIP-8-300-2.54
avoid saturation, the peak current compensation will decrease for
balance after power-on.
It integrates various protections such as undervoltage lockout,
overvoltage protection, overload protection, lead edge blanking,
primary winding overcurrent protection and thermal shutdown. The
circuit will restart until normal if protection occurs.
APPLICATIONS
