LM2599T-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2599T-ADJ/NOPB is a SIMPLE SWITCHER® power converter from Texas Instruments, functioning as an adjustable step-down switching voltage regulator. It operates with a fixed switching frequency of 150 kHz and supports an input voltage range of 4.5 V to 40 V. The device delivers a maximum output current of 3 A with an adjustable output voltage range spanning from 1.2 V to 37 V. Designed for through-hole mounting, it utilizes a TO-220-5 package. The component ensures reliable performance across an extended operating temperature range from -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status directly on the manufacturer's official datasheet or product page. Confirm the package type matches the required TO-220-5 footprint for your PCB layout. Ensure the adjustable output variant aligns with your voltage reference resistor selection needs rather than fixed voltage options.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a high-current 3 A step-down solution is required in a through-hole package. It is suitable for designs needing an input voltage up to 40 V and an adjustable output down to 1.2 V. Consider the 150 kHz switching frequency for balancing component size and efficiency against noise sensitivity in your application environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2599 series of SIMPLE SWITCHER power converters. It shares architectural similarities with the LM2596 and LM2598 families but offers distinct current handling capabilities. The series is characterized by its simplicity, requiring minimal external components to achieve stable regulated output voltages for various industrial and commercial power management tasks.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations
