Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2592HVS-3.3/NOPB

LM2592HVS-3.3/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2592HVS-3.3/NOPB is a SIMPLE SWITCHER power converter from Texas Instruments, functioning as a step-down voltage regulator with a fixed 3.3 V output. It supports an input voltage range of 4.5 V to 60 V and delivers up to 2 A of output current. The device operates at a switching frequency of 150 kHz and utilizes a TO-263-5 package for surface mount installation. It features internal overcurrent protection and shutdown capabilities, operating within a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated high-voltage switch rated for 60 V input
Fixed 3.3 V output configuration
Internal frequency compensation for minimal external components
Thermal shutdown and current limit protection

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation in distributed power systems
Pre-regulator stages for downstream linear regulators
Efficient buck conversion for battery-powered equipment

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free composition and RoHS compliance. Confirm the TO-263-5 package variant matches the design footprint. Ensure the fixed 3.3 V output aligns with load requirements, as adjustable versions exist within the same family. Check datasheet for humidity sensitivity handling during assembly.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3 V output is required from a high-voltage source up to 60 V. The 2 A current rating suits moderate power applications. Consider the TO-263-5 package for thermal performance and board space constraints. Verify that the 150 kHz switching frequency fits EMI requirements compared to higher-frequency alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2592HV series of SIMPLE SWITCHER converters. It shares architectural similarities with the LM2591HV but offers higher current capability. The 'S' suffix denotes the surface-mount TO-263 package, while 'NOPB' specifies non-plumbum (lead-free) construction compliant with environmental directives.
