Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2618ATL

LM2618ATL

Voltage Regulators - DC DC Switching Regulators Overview

The LM2618ATL is a synchronous step-down DC-DC converter manufactured by Texas Instruments. It operates with an input voltage range of 2.7V to 5.5V and provides a programmable output voltage. The device delivers up to 400mA of output current and integrates a fixed switching frequency of 600kHz. It features a low quiescent current of 350µA and supports shutdown mode for power conservation. The component is housed in a 10-pin WFBGA package and is rated for operation between -40°C and +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Synchronous rectification architecture for high efficiency
Programmable output voltage via external resistors
Integrated power switch and control circuitry
Thermal shutdown protection

Voltage Regulators - DC DC Switching Regulators Applications

Portable battery-powered devices
Embedded systems requiring stable low-voltage rails
Industrial control modules

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix and tape/reel configuration against the manufacturer's latest datasheet, as packaging options may vary. Confirm RoHS compliance status and lead-free material declarations directly from official documentation before integration into production designs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution for stepping down 3.3V or 5V sources is required. Ensure the load current does not exceed 400mA and that the PCB layout accommodates the thermal requirements of the WFBGA package for optimal performance.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2618 family of synchronous buck converters. It is designed for applications needing efficient power conversion from standard battery voltages. The device replaces older non-synchronous regulators to improve system efficiency and reduce heat generation in space-constrained environments.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for direct pin-compatible alternatives within the same family or newer generations from Texas Instruments. Verify that any substitute maintains the 600kHz switching frequency and 400mA current capability to ensure circuit stability.
