Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2588S-3.3

LM2588S-3.3

Voltage Regulators - DC DC Switching Regulators Overview

The LM2588S-3.3 is a SIMPLE SWITCHER step-up wide VIN flyback regulator manufactured by Texas Instruments. It provides a fixed 3.3 V output with a maximum output current of 5 A. The device operates from an input voltage range of 4 V to 40 V and supports a switching frequency of 200 kHz. It is housed in a TO-263-7 surface-mount package and functions within a temperature range of -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated flyback topology for high-voltage step-up applications
Built-in shutdown capability for power management control
Fixed 3.3 V output configuration for standard logic levels

Voltage Regulators - DC DC Switching Regulators Applications

Wide input voltage DC-DC conversion systems
Industrial power supply designs requiring flyback regulation
Battery-powered equipment needing step-up voltage regulation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (e.g., NOPB) against the manufacturer's current datasheet to confirm RoHS compliance and pinout compatibility. Ensure the TO-263-7 package variant matches the target PCB footprint. Cross-reference the 3.3 V fixed output specification to prevent selection errors with adjustable or other voltage variants within the same family.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a wide input voltage range up to 40 V is required for step-up applications. The 5 A output current capacity suits moderate power loads. Consider the 200 kHz switching frequency for balancing efficiency and external component size. Verify thermal performance requirements given the TO-263 package constraints for continuous operation.

Voltage Regulators - DC DC Switching Regulators Part Context

The LM2588 series belongs to Texas Instruments' SIMPLE SWITCHER line, designed for simplified power supply development. This specific model utilizes a flyback architecture, distinguishing it from standard buck or boost converters. It integrates the controller and power switch, reducing external component count compared to discrete solutions.
