Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2599SX-3.3/NOPB

LM2599SX-3.3/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2599SX-3.3/NOPB is a SIMPLE SWITCHER power converter from Texas Instruments, functioning as a 150 kHz step-down voltage regulator. It provides a fixed 3.3 V output with a maximum load current of 3 A. The device operates within an input voltage range of 4.5 V to 40 V and supports junction temperatures from -40 °C to +125 °C. Packaged in the D2PAK (TO-263) surface-mount format, it integrates a 150 kHz oscillator for efficient DC-DC conversion.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated 150 kHz fixed-frequency oscillator eliminates external timing components
Internal error amplifier ensures tight output voltage regulation under varying loads
Built-in thermal shutdown circuitry protects against overheating during fault conditions

Voltage Regulators - DC DC Switching Regulators Applications

Distributed power supply architectures requiring high efficiency
Pre-regulator stages for switching regulators
Battery-powered systems needing step-down conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status. Confirm the package designation matches the required D2PAK footprint. Ensure the fixed 3.3 V output variant aligns with the target circuit design requirements before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3 V output at up to 3 A is required without external feedback resistors. The integrated oscillator simplifies design compared to adjustable counterparts. Consider the thermal performance of the D2PAK package for heat dissipation needs in the application environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2599 series of SIMPLE SWITCHER converters. It shares the core architecture with other variants like the LM2599SX-5.0 but differs in its fixed output voltage setting. The series is designed for general-purpose step-down applications with high efficiency and minimal external component count.
