LM2594HVN-3.3/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2594HVN-3.3/NOPB is a step-down switching regulator from the SIMPLE SWITCHER family, manufactured by Texas Instruments. It operates with an input voltage range of 4.5 V to 60 V and provides a fixed 3.3 V output at up to 500 mA. The device utilizes a buck topology with a typical switching frequency of 150 kHz. It is housed in an 8-pin PDIP package and supports an operating junction temperature range from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated power switch rated for high input voltages up to 60 V
• Fixed 3.3 V output option eliminates external feedback resistor networks
• Internal frequency compensation simplifies external component requirements
• Thermal shutdown protection safeguards against overheating

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for industrial control systems
• Power supply stages for embedded computing hardware
• Voltage conversion for automotive electronics subsystems

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'N' confirms the through-hole PDIP-8 package variant rather than surface-mount options. Confirm the '-3.3' designation specifies the fixed 3.3 V output version. Ensure the '/NOPB' indicates lead-free and RoHS compliance status as required by project specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a robust 60 V input tolerance is required alongside a fixed low-voltage output. The PDIP-8 package suits prototyping or applications where manual assembly is preferred over automated SMT processes. Consider thermal management needs given the single-output configuration and through-hole construction constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2594HV series, designed for high-voltage step-down applications. It serves as a direct replacement for older discrete solutions requiring high input voltage handling. The SIMPLE SWITCHER architecture reduces design complexity compared to standard PWM controllers.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2594HVN-ADJ/NOPB offers adjustable output instead of fixed 3.3 V. LM2594MX-3.3/NOPB provides the same electrical performance but in a surface-mount SOIC-8 package.
