资 源 简 介
The LM2575 series of regulators are monolithic integrated circuits that provide all the acTIve funcTIons for a step-down (buck) switching regulator, capable of driving a 1A load with excellent line and load regulaTIon
• 3.3V, 5V, 12V, 15V, and adjustable output versions • Adjustable version output voltage range, 1.23V to 37V (57V for HV version) ±4% max over line and load condiTIons • Guaranteed 1A output current • Wide input voltage range, 40V up to 60V for HV version • Requires only 4 external components • 52 kHz fixed frequency internal oscillator • TTL shutdown capability, low power standby mode • High efficiency • Uses readily available standard inductors • Thermal shutdown and current limit protection • P + Product Enhancement tested
