DESCRIPTION
In standby mode, the circuit enters burst mode to reduce the standby power dissipation. Built-in peak current compensation circuit makes the limit peak current stable even with different input AC voltage. Built-in limit output power compensation circuit to balance the limit output power under different AC voltage inputs. Built-in slope compensation circuit to adapt to more transformer applications. Maximum peak current compensation during power-on reduces pressure on transformer to avoid saturation, the peak current compensation will decrease for balance after power-on. Limit output current can be APPLICATIONS
adjusted through the resistor connected to CS. It integrates various protections such as undervoltage lockout, ∗ SMPS overvoltage protection, overload protection, leading edge blanking and thermal shutdown. The circuit will restart until normal if protection occurs. FEATURES
∗ Energy Star 2.0 standard ∗ Lower start-up current (4µA) ∗ Various switching frequency follow...
