SD4843, SD4840, PWM Controller
SD4840/4841/4842/4843/4844 is a current mode PWM controller 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 67KHz with ±2.5 KHz jitter frequency for low EMI.
The stress on t
