LM2576HVS-5.0

The LM2576HVS-5.0 is designed as one kind of high efficiency 3A step-down voltage regulator that can be used in (1)Simple to design, high efficiency (>90%) step-down switching regulators; (2)Efficient system pre-regulator for linear voltage regulators; (3)Battery chargers applications. And this device also has built in thermal shutdown, current limiting and an ON/OFF control input that can power down the regulator to a low 50A quiescent current standby condition.

Features of the LM2576HVS-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 Guaranteed 3A output current; (3)Wide input voltage range, 40V up to 60V for HV version; (4)Requires only 4 external components; (5)52 kHz fixed frequency internal oscillator; (6)TTL shutdown capability, low power standby mode; (7)High efficiency; (8)Uses readily available standard inductors; (9)Thermal shutdown and current limit protection; (10)P+ Product Enhancement tested.

The absolute maximum ratings of the LM2576HVS-5.0 can be summarized as:(1)Maximum Supply Voltage: 63 V;(2)ON/OFF Pin Voltage: -0.3V V +VIN;(3)Output Voltage to Ground (Steady State): -1 V;(4)Power Dissipation: Internally Limited;(5)Storage Temperature Range: -65°C to 150°C;(7)Maximum Junction Temperature: 150°C;(8)Minimum ESD Rating: 2 kV;(9)Lead Temperature (Soldering, 10 Seconds): 260°C.
