TheLM5001SDE/NOPB (购买请点击)high voltage switch mode regulator features allof the functions necessary to implement efficient high voltageBoost, Flyback, SEPIC and Forward converters, using fewexternal components. This easy to use regulator integrates a75 Volt N-Channel MOSFET with a 1 Amp peak current limit.Current mode control provides inherently simple loop compensationand line-voltage feed-forward for superior rejectionof input transients. The switching frequency is set with a singleresistor and is programmable up to 1.5MHz. The oscillatorcan also be synchronized to an external clockLM5001SDE/NOPB (购买请点击). Additional protectionfeatures include: current limit, thermal shutdown, under-voltage lockout and remote shutdown capability. Thedevice is available in both SO-8 and LLP-8 packagesLM5001SDE/NOPB (购买请点击).
