D8550VF TO-255 固态继电器 PWM IC+场效应管过压保护

  The D8550VF integrated a current mode PWM controller and a high voltage power MOSFET, which is applied to power less than 3 0 W. D8550VF operates in the f i xed frequency at heavy load and operates in Green Mode at no load or light load . Slope compensation circuit is integrated in D8550VF, which improves system large signal stability and reduces the possible sub- harmonic oscillation at high PWM duty cycle . Leading- edge blanking on current sense input eliminates the signal glitch due to sunbber circuit diode reverse recovery current . Frequency Shuffling technique is integrated in D8550VF, which helps to achieve excellent EMI performance . D8550VF offers complete protection functions with auto recovery including cycle- by- cycle current limiting protection ( OCP) , over load protection ( OLP) , VDD over voltage protection( OVP) , VDD over voltage clamp and under voltage lockout ( UVLO) . Driven by internal totem pole can improve the EMI characteristics of the system and the soft start control of the switch . D8550VF is offered in TO-25 5 Pb-free package
