LM2599T-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2599T-5.0/NOPB is a SIMPLE SWITCHER power converter featuring an integrated 3A step-down voltage regulator with a fixed 5.0V output. It operates from a 4.5V to 40V input range at a 150kHz switching frequency. The device utilizes pulse width modulation control and includes internal frequency compensation and a 150mA oscillator-driven reference. It is housed in a TO-220-7 ZIP package, rated for operation between -40°C and 125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a high-current switch capable of delivering up to 3A load current
• Includes built-in thermal shutdown and current limit protection circuits
• Requires minimal external components for standard buck topology implementation

Voltage Regulators - DC DC Switching Regulators Applications

• Distributed power supply systems requiring efficient step-down conversion
• Pre-regulator stages for linear post-regulator architectures
• Efficient on-card regulation for board-level DC-to-DC conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free construction compliant with RoHS standards. Confirm the TO-220-7 ZIP package matches the target PCB footprint. Ensure the fixed 5.0V output variant aligns with system requirements rather than adjustable versions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required with up to 3A capacity. The TO-220-7 package provides robust thermal dissipation for high-current applications. Verify that the 40V maximum input voltage accommodates the highest expected line conditions without exceeding ratings.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2599 family of SIMPLE SWITCHER regulators. It shares core architecture with other variants like the LM2598 and LM2596 but offers higher current capability. The T suffix denotes the through-hole TO-220-7 ZIP package, while the 5.0 specifies the fixed output voltage.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2599T-5.0 is the direct lead-free equivalent. LM2599T-ADJ/NOPB serves as an alternative if variable output voltage is needed using identical packaging.
