Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2578AN

LM2578AN

Voltage Regulators - DC DC Switching Regulators Overview

The LM2578AN is a monolithic integrated circuit step-up/step-down/buck-boost switching regulator manufactured by Texas Instruments. It operates from an input voltage range of 4.5V to 40V and provides a regulated output current up to 0.75A. The device utilizes pulse-width modulation (PWM) control with a fixed internal switching frequency of 52kHz. It is housed in a standard 8-pin DIP package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated high-current power switch rated for 0.75A output
Fixed 52kHz switching frequency eliminates need for external timing components
Supports buck, boost, and buck-boost topologies for versatile voltage conversion

Voltage Regulators - DC DC Switching Regulators Applications

Battery-powered systems requiring voltage regulation
DC-to-DC converter circuits
Negative voltage generation applications

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm pinout compatibility and thermal characteristics. Ensure the selected variant matches the required operating temperature range and packaging style for your design constraints.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a simple, cost-effective solution for moderate current DC-DC conversion is needed. Consider the fixed 52kHz frequency for EMI management and verify that the 0.75A output current meets the load requirements without excessive heat dissipation.

Voltage Regulators - DC DC Switching Regulators Part Context

Part of the LM257x family of switching regulators, designed for ease of use with minimal external components. This series is widely used in industrial and commercial power supply designs where efficiency and simplicity are prioritized over ultra-low quiescent current.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for LM2578N or LM2578AM variants for equivalent functionality with different temperature ratings or package options. Verify cross-reference availability through authorized distributors.
