LM2596S-5.0 Buck Regulator
3A Continuous Output meets 5.0V Fixed Precision – The Industry-Standard SIMPLE SWITCHER® Power Silicon Choice for Industrial Control Mainboards and Reliable Step-Down Modules.
// 150kHz Fixed Frequency Built-in 3A Power Switch TO-263-5 DDPAK Portfolio
The Time-Tested Non-Isolated Step-Down Advantage
The LM2596S-5.0 represents a premier professional TO-263 (DDPAK) packaged monolithic PWM step-down buck DC-DC converter solution engineered for space-constrained, high-throughput hardware architectures demanding absolute power conversion efficiency and minimum external component counts. Built on Texas Instruments’ legendary SIMPLE SWITCHER® technology framework operating at a deterministic 150 kHz frequency node, this module processes high-current load lines up to 3A continuous flawlessly without excessive thermal runaway hazards or systemic performance lagging. Housed in an industry-standard 5-pin surface mount layout, it secures pure, deterministic power routing loops and completely cuts off circuit layout overhead bottlenecks.
- Guaranteed 3A continuous load output current capability under diverse environmental gradients cleanly
- Fixed 5.0V precision output loop eliminating external feedback resistor calibration networks safely
- Requires only 4 external passive parts to build a complete high-efficiency switching power station smoothly
Key Performance Advantages
3A Symmetrical Drive
Maintains excellent line and load regulation loops, continuously driving heavy 5V logic networks and relay boards safely under industrial parameters.
Full Thermal Safeguards
Integrates two-stage thermal shutdown limits and cycle-by-cycle current limit thresholds, shielding downstream circuitry against accidental shorts safely.
TO-263 Surface Mount
Housed inside a standard DDPAK surface-mount enclosure featuring a large backside heat-sink tab, optimizing board real estate scaling smoothly.
