LM2592HVT-3.3/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2592HVT-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. Operating at a typical switching frequency of 150 kHz, the device utilizes a TO-220-5 package for surface-mount or through-hole integration. The component features a maximum duty cycle of 100% and includes internal overcurrent protection.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T' indicates the TO-220 package variant distinct from the SMD 'VS' version. Confirm RoHS compliance via the NOPB designation. Ensure the fixed 3.3 V output matches system requirements, as adjustable variants exist within the same family. Cross-reference datasheet revision dates for updated electrical characteristics.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 3.3 V rail is required with up to 2 A load capacity. The TO-220 package offers robust thermal performance for higher power dissipation compared to smaller footprints. Consider the 60 V input tolerance for noisy automotive or industrial environments. Evaluate thermal management needs based on the voltage differential between input and output.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2592HV series, designed for high-voltage buck applications. It shares architectural similarities with the LM2591 and LM2594 families but differs in output current ratings and package options. The SIMPLE SWITCHER line emphasizes ease of design with minimal external components.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM2592HVS-3.3/NOPB for surface-mount implementations. For adjustable output requirements, consider LM2592HV-ADJ variants. Verify pin compatibility and thermal resistance specifications when transitioning between package types.
