The Texas Instruments LM2597HVM-ADJ/NOPB is a monolithic integrated circuit designed for step-down (buck) switching regulator applications. It is capable of driving a 0.5-A load with excellent line and load regulation.
This regulator features an adjustable output voltage range from 1.2 V to 37 V (57 V for HV version) with ±4% maximum variation over line and load conditions. It operates at a fixed switching frequency of 150 kHz, allowing for smaller external filter components. The device includes features such as shutdown/soft-start and an out-of-regulation error flag.
Packaged in an 8-pin SOIC surface-mount package, the LM2597HVM-ADJ/NOPB is designed for ease of use with minimal external components. Its high efficiency typically requires only the printed-circuit board copper traces for heat sinking. The operating temperature range is -40°C to 125°C (TJ).
Key applications include simple high-efficiency step-down regulators, efficient preregulators for linear regulators, and on-card switching regulators. It also supports positive-to-negative conversion.
