Description :
SD4840 / SD4841 / SD4842 / SD4843 / SD4844 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.
Pinout

The switch frequency is 67KHz with ±2.5 KHz jitter frequency for low EMI.
Features
1. Lower start-up current (Typ.6μA)
2. Frequency jitter for low EMI
3. Overcurrent protection
4. Overvoltage protection
5. Undervoltage lockout
6. Built-in temperature protection
7. Built-in high voltage MOSFET
