The LM2574HVN from Texas Instruments is a monolithic integrated circuit that functions as a step-down (buck) switching regulator. It is designed to drive a 0.5A load with excellent line and load regulation.
This adjustable output version offers a voltage range from 1.23V to 37V, with HV versions supporting up to 57V. The device features a wide input voltage range, up to 60V for HV variants, and requires minimal external components. It operates at a fixed frequency of 52kHz, includes internal frequency compensation, and provides TTL shutdown capability for low-power standby modes.
Designed for high efficiency, the LM2574HVN can serve as a replacement for linear regulators. The copper traces on a PCB are typically sufficient for heat sinking. The regulator includes built-in thermal shutdown and current-limit protection.
Packaged in an 8-pin PDIP, the LM2574HVN is suitable for various power management applications. It operates within a temperature range of -40°C to 125°C.
