SD4841
Overview
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.
- Lower start-up current (Typ.6μA) * Frequency jitter for low EMI * Overcurrent protection * Overvoltage protection * Undervoltage lockout * Built-in temperature protection * Built-in high voltage MOSFET * Auto restart mode * Built-in soft start * Burst mode operation * Cycle by cycle current limit
