LM2588SX-12

Voltage Regulators - DC DC Switching Regulators Overview

The LM2588SX-12/NOPB is a SIMPLE SWITCHER step-up wide VIN flyback regulator from Texas Instruments. It operates with an input voltage range of 4 V to 40 V and provides a fixed 12 V output. The device supports up to 6.5 A output current and utilizes a 200 kHz switching frequency. Packaged in a TO-263-7 (D2PAK) surface-mount housing, it functions within a temperature range of -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated high-voltage power switch designed for flyback topology applications
• Fixed 12 V output configuration simplifies external component selection
• Operates over a wide 4 V to 40 V input voltage range

Voltage Regulators - DC DC Switching Regulators Applications

• Industrial control systems requiring isolated power supplies
• Automotive electronics operating on 12 V or 24 V nominal buses
• Telecommunications equipment power distribution

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free compliance and RoHS adherence. Confirm the SX package variant matches the required thermal dissipation needs for the specific load. Ensure the fixed 12 V output aligns with system requirements as no adjustable versions share this exact part number.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12 V isolated output is required from a wide input range. The TO-263-7 package offers superior thermal performance compared to smaller footprints. Verify that the 6.5 A capability meets peak load demands while accounting for efficiency losses at higher input voltages.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2588 family of SIMPLE SWITCHER regulators. These devices are engineered for high-efficiency DC-DC conversion using flyback topologies. The series targets applications needing galvanic isolation and robust performance across varying line conditions.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2588SX-12/NOPB serves as the direct lead-free replacement for the older LM2588SX-12. Both parts share identical electrical specifications and pinouts. Verify that any alternative flyback controllers require external driver stages.
