LM2575T-5.0

The LM2575T-5.0 is designed as one kind of 1A step-down voltage regulator that provide all the active functions for step-down  switching regulator ,capable of driving a 1A load with excellent line and load regulation.These devices are available in fixed output voltages of 3.3V, 5V, 12V, 15V, and an adjustable output version.It offers a high-efficiency replacement for popular three-terminal linear regulators.Also it substantially reduces the size of the heat sink, and in many cases no heat sink is required.

Features of the LM2575T-5.0 are:(1)3.3V, 5V, 12V, 15V, and adjustable output versions;(2)adjustable version output voltage range, 1.23V to 37V (57V for HV version) ±4% max over line and load conditions;(3)guaranteed 1A output current;(4)wide input voltage range, 40V up to 60V for HV version;(5)requires only 4 external components;(6)52 kHz fixed frequency internal oscillator;(7)TTL shutdown capability, low power standby mode;(8)high efficiency;(9)uses readily available standard inductors;(10)thermal shutdown and current limit protection;(11)P+ product enhancement tested.It can be used in simple high-efficiency step-down (buck) regulator,efficient pre-regulator for linear regulators,on-card switching regulators and positive to negative converter (Buck-Boost).

The absolute maximum ratings of the LM2575T-5.0 can be summarized as:(1)maximum supply voltage:45 V;(2)output voltage to ground:-1 V;(3)power dissipation:internally limited;(4)storage temperature range:-65°C to +150°C;(5)maximum junction temperature:150°C;(6)minimum ESD rating(C=100 pF,R=1.5 k):2kV;(7)lead temperature(soldering,10 sec.):260°C.If you want to know more information such as the electrical characteristics about the LM2575T-5.0,please download the datasheet in www.seekdatasheet.com or www.chinaicmart.com.
