LM2590HVT-3.3/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2590HVT-3.3/NOPB is a SIMPLE SWITCHER power converter from Texas Instruments, configured as a fixed-output buck regulator with a 3.3 V output. It supports an input voltage range up to 60 V and delivers a maximum output current of 1 A. Operating at a fixed switching frequency of 150 kHz, the device utilizes a TO-220-7 through-hole package. The unit functions within a junction temperature range of -40 °C to +125 °C and maintains a quiescent current of 5 mA.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'NOPB' confirms lead-free and RoHS compliance status per the manufacturer's latest documentation. Confirm the 'VT' designation corresponds to the specified TO-220-7 through-hole package variant rather than surface-mount alternatives. Cross-reference the specific datasheet revision to ensure thermal performance data matches the intended application environment.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3 V rail is required from high-voltage inputs up to 60 V. The through-hole TO-220-7 package facilitates manual assembly and robust thermal dissipation for moderate load currents. Ensure the application does not require adjustable output voltages or synchronous rectification, which are features found in other variants within the LM2590HV family.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2590HV series of SIMPLE SWITCHER regulators, designed for high-input voltage applications. Unlike standard LM2590 devices, the HV variant accommodates input voltages up to 60 V. The LM2590HVT-3.3/NOPB specifically provides a fixed 3.3 V output in a through-hole package, distinguishing it from the SMD HVS and HVM series members.
