LM2588S-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2588S-5.0/NOPB is a fixed-output flyback switching voltage regulator from Texas Instruments, designed for step-up applications with an input range of 4 V to 40 V. It provides a fixed 5 V output at a maximum current of 5 A. The device operates at a switching frequency of 200 kHz and features a TO-263 (D2PAK) surface-mount package. It supports operation across a temperature range of -40 °C to +125 °C, with line and load regulation specified at 50 mV.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated flyback topology suitable for wide input voltage ranges
• Fixed 5 V output configuration for simplified design
• High efficiency switching operation up to 5 A load

Voltage Regulators - DC DC Switching Regulators Applications

• Industrial power supplies requiring isolated or non-isolated step-up conversion
• Battery-powered systems needing voltage boost from low source voltages
• General-purpose DC-DC conversion in automotive or telecom equipment

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix 'NOPB' indicates lead-free/RoHS compliance as per Texas Instruments standards. Confirm the package type is TO-263 (D2PAK) for PCB layout compatibility. Ensure the fixed 5.0 V output matches system requirements, as adjustable variants exist within the same family. Check for moisture sensitivity level (MSL) handling requirements during storage and assembly.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from a 4–40 V input source. The 5 A current capability suits moderate-power applications. Consider the 200 kHz switching frequency for trade-offs between component size and EMI. The TO-263 package offers thermal performance advantages over smaller packages but requires adequate copper area for heat dissipation.

Voltage Regulators - DC DC Switching Regulators Part Context

Part of the LM2588 SIMPLE SWITCHER family, which includes adjustable and other fixed-voltage variants. The LM2588 series is designed for high-efficiency flyback converters. The 'S' suffix denotes the TO-263 package, while '5.0' specifies the fixed output voltage. 'NOPB' signifies Pb-free/RoHS compliant manufacturing.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2588SX-12/NOPB: Different fixed output voltage (12 V vs 5 V). LM2588S-ADJ/NOPB: Adjustable output variant instead of fixed 5 V. LM2598S-5.0/NOPB: Buck converter topology, not compatible with flyback step-up applications.
