LM2594HVM-12/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2594HVM-12/NOPB is a SIMPLE SWITCHER step-down voltage regulator from Texas Instruments. It operates with an input voltage range of 4.5 V to 60 V and provides a fixed 12 V output at up to 500 mA. The device utilizes a buck topology with a switching frequency of 150 kHz. It is housed in an 8-pin SOIC surface-mount package. The component supports a shutdown function and functions within a junction temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated power switch enables low external component count for compact designs
• Fixed 12 V output eliminates the need for external feedback resistors
• Internal frequency compensation simplifies circuit layout and design

Voltage Regulators - DC DC Switching Regulators Applications

• Distributed power supply systems requiring high input voltage tolerance
• On-board regulation for bus voltages exceeding standard levels
• Pre-regulator stages for downstream switching regulators

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'HVM' confirms the high-voltage variant with SOIC packaging and fixed 12 V output. Confirm the '/NOPB' designation indicates lead-free and RoHS compliance. Ensure the manufacturer is Texas Instruments, as this part belongs to the SIMPLE SWITCHER family. Cross-reference the datasheet for thermal performance requirements under your specific load conditions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12 V output is required from inputs up to 60 V. The 500 mA current limit suits moderate power applications. Consider the SOIC package for surface-mount assembly. Compare against the adjustable version if variable output is needed, or the through-hole N variant if PCB mounting style differs.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2594HV series, designed for high-input voltage applications. It is part of the SIMPLE SWITCHER family, which integrates the controller, power switch, and freewheeling diode into a single monolithic IC. This integration reduces the number of external components compared to discrete solutions.
