Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2575HVS-15/NOPB

LM2575HVS-15/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575HVS-15/NOPB is a SIMPLE SWITCHER® 1A step-down voltage regulator manufactured by Texas Instruments. It operates with a fixed 15V output and supports an input voltage range up to 60V. The device features a 52kHz internal oscillator, voltage-mode control, and pulse width modulation. It is housed in a TO-263 (DDPAK-5) surface-mount package. Key electrical parameters include a maximum switching frequency of 63kHz, a typical quiescent current of 10mA, and operation within a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated high-voltage power switch capable of driving 1A loads
Fixed-frequency internal oscillator for simplified design
Built-in thermal shutdown and cycle-by-cycle current limiting
TTL shutdown pin for low-power standby modes

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for industrial systems
Pre-regulator stages for switching regulators
Efficient buck converters replacing linear regulators
Battery-powered systems requiring wide input ranges

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation as Texas Instruments, which acquired National Semiconductor. Confirm the suffix NOPB indicates lead-free and RoHS compliance. Ensure the package matches the specified TO-263 form factor. Cross-reference datasheets for the specific HV variant specifications rather than standard versions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for applications requiring a fixed 15V output from inputs up to 60V. It is suitable where a 1A continuous load current is needed without external pass transistors. Consider the TO-263 package for thermal management needs. Verify compatibility with standard inductor values optimized for the 52kHz switching frequency.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2575 family of monolithic integrated step-down switching regulators. The 'HV' suffix denotes the high-voltage version supporting inputs up to 60V, compared to the standard 40V limit. The 'S' indicates the surface-mount TO-263 package. This series provides a direct replacement for many three-terminal linear regulators.
