开关电源用功率IC

STR3A400HDL系列，是功率MOSFET和电流模式PWM控制IC封装在一起的开关电源用功率IC。\n 为了对应低消耗功率及低待机功耗，启动电路和待机功能内置。正常动作时PWM动作、轻负载时向Burst间隙动作自动切换。增强的保护功能，构成部品少，可以很容易构成高性价比的电源系统。 高散热性能封装电路效率改善\n（由于Step Drive分步驱动，二次侧整理Diode和原来相比可以选用低耐压品，从而实现低VF化）低噪声电流模式PWM控制软启动功能自动待机功能\n无负载时输入功率PIN 动作模式\n正常时 PWM模式\n轻负载时Green模式\n待机时Burst振荡模式随机开关功能斜率补偿功能（防止次谐波振荡）LEB前沿消隐功能Bias-Assist功能保护功能\n过电流保护（OCP）\n过负载保护（OLP）\n过电压保护（OVP）\n过热保护（TSD）;
