Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2595S-3.3

LM2595S-3.3

Voltage Regulators - DC DC Switching Regulators Overview

The LM2595S-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 3.3V output with a maximum current of 1A. The device accepts an input voltage range of 4.5V to 40V. It utilizes a TO-263 (D2PAK) surface-mount package with five pins plus a thermal pad. Operating junction temperature ranges from -40°C to +125°C. Static supply current is typically 5 mA.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated monolithic buck switching regulator topology
Fixed internal feedback network for standard voltage outputs
Built-in frequency compensation and thermal shutdown protection

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for embedded systems
Pre-regulation stages for linear regulators
Battery-powered equipment power conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix /NOPB indicates lead-free/RoHS compliance. Confirm the package variant matches the required footprint, as TO-263 variants exist. Ensure the specific output voltage code corresponds to the design requirement, as the base model number may denote adjustable or other fixed voltages in different configurations.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 1A buck converter is required with a wide input range up to 40V. The fixed 3.3V output eliminates external resistor networks. Consider the thermal performance of the TO-263 package for heat dissipation requirements in the target application environment.

Voltage Regulators - DC DC Switching Regulators Part Context

Part of the LM2595 SIMPLE SWITCHER family, designed for high-efficiency DC-DC conversion. It serves as a lower-current alternative to the LM2596 series, which supports higher currents. The device simplifies power supply design by integrating the controller, switch, and freewheeling diode into a single IC.
