SD6835 controller equivalent, current mode pwm+pfm controller.
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 decid.
Maximum peak
current compensation during power-on reduces pressure on
transformer to avoid saturation, the peak curre.
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.
