LM2575HVS-5.0/NOPB

The LM2575HVS-5.0/NOPB is an optimized power management IC that includes a 52kHz fixed-frequency internal oscillator and all active functions required for power conversion. Its high efficiency significantly reduces heat generation, often eliminating the need for bulky heatsinks. The device features robust fault protection, including thermal shutdown and cycle-by-cycle current limiting. It is particularly suited for high-voltage industrial applications, supporting input voltages from 4.75V to as high as 60V, while maintaining precise output voltage regulation.

Features:

• High Efficiency:ÊSuperior efficiency over linear regulators reduces power loss and cooling requirements.
• Minimal Components:ÊRequires only four external components (inductor, catch diode, and two capacitors) for a complete circuit.
• High Input Range:ÊHV (High Voltage) version supports inputs up to 60V.
• Internal Protection:ÊFeatures integrated thermal shutdown and current limit protection.
• Shutdown Capability:ÊIncludes TTL shutdown capability with a low-power standby modeÊ
• Fixed Frequency: Operates with a stable 52kHz internal oscillator to simplify filter design.

Package Includes:

• 1 x LM2575HVS-5.0/NOPB 1A Step-Down Voltage Regulator (TO-263-5 / D2PAK Package).
