Product Summary
The LM2575S-5.0 is a 1A Step-Down Voltage Regulator. It offers a high-efficiency replacement for popular three-terminal linear regulators. It substantially reduces the size of the heat sink, and in many cases no heat sink is required.
Parametrics
Absolute maximum ratings: (1)Maximum Supply Voltage:45V; (2)ON /OFF Pin Input Voltage:-0.3V ≤ V ≤ +VIN; (3)Output Voltage to Ground(Steady State):-1V; (4)Power Dissipation:Internally Limited; (5)Storage Temperature Range:-65℃ to +150℃; (6)Maximum Junction Temperature:150℃.
Features
Features: (1)Guaranteed 1A output current; (2)Wide input voltage range, 40V up to 60V for HV version; (3)Requires only 4 external components; (4)52 kHz fixed frequency internal oscillator; (5)TTL shutdown capability, low power standby mode; (6)High efficiency; (7)Uses readily available standard inductors; (8)Thermal shutdown and current limit protection; (9)P+ Product Enhancement tested.
