LM2574N-5.0

The LM2574N-5.0 is one of The LM2574 series. The LM2574 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down(buck) switching regulator, capable of driving a 0.5A 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.

Features of the LM2574N-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 0.5A 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.

The absolute maximum ratings of the LM2574N-5.0 can be summarized as:(1)Maximum Supply Voltage LM2574:45V; (2)ON /OFF Pin Input Voltage:-0.3V V +VIN; (3)Output Voltage to Ground(Steady State): -1V; (4)Minimum ESD Rating(C = 100 pF, R = 1.5 k):2kV; (5)Storage Temperature Range: -65 to +150.If you want to know more information such as the electrical AC characteristics ,please download the datasheet in www.seekdatasheet.com .
