LM2591HVT-3.3

Voltage Regulators - DC DC Switching Regulators Overview

The LM2591HVT-3.3 is a SIMPLE SWITCHER power converter from Texas Instruments, functioning as a step-down voltage regulator with a fixed 3.3 V output and 1 A maximum output current. It operates at a switching frequency of 150 kHz and supports an input voltage range up to 60 V. The device utilizes a TO-220-5 package and is rated for an operating temperature range from -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated monolithic switching regulator designed for high-efficiency step-down conversion
Fixed internal oscillator eliminates the need for external timing components
Built-in thermal shutdown circuitry protects against excessive junction temperatures

Voltage Regulators - DC DC Switching Regulators Applications

Distributed power supply systems requiring buck conversion
Pre-regulator circuits for downstream switching regulators
Efficient on-card regulation from bus voltages

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'HVT' corresponds to the TO-220-5 through-hole package variant rather than surface-mount options. Confirm that the fixed 3.3 V output version meets the target application requirements before procurement, as adjustable variants exist within the same family.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3 V output is required with up to 1 A load capability. Ensure the design accommodates the 150 kHz switching frequency and verify that the TO-220-5 package provides adequate thermal dissipation for the expected ambient conditions and duty cycle.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2591HV series, which offers higher input voltage tolerance compared to standard LM2591 devices. It shares functional similarities with the LM2592 and LM2593 series but is distinguished by its 1 A output current rating and specific package configuration.
