D8545HF SOP8 SSR IC+MOSFET 12W

  The D8545HF integrated a current mode PWM controller and a high voltage power MOSFET, which is applied to power less than 10W. D8545HF operates in the fixed frequency at heavy load and operates in Green Mode at no load or light load.Slope compensation circuit is integrated in D8545HF, 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 snubber circuit diode reverse recovery current. Frequency Shuffling technique is integrated in D8545HF, which helps to achieve excellent EMI performance. D8545HF offers complete protection functions with autorecovery 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. D8545HF is offered in SOP8 Pb-free package
