TPS54395RSAR

Voltage Regulators - DC DC Switching Regulators Overview

The TPS54395RSAR is a dual-output synchronous step-down switching regulator manufactured by Texas Instruments. It operates with an input voltage range of 4.5 V to 18 V and provides two adjustable output channels, each capable of delivering up to 3 A. The device utilizes the D-CAP2 control architecture for stable operation without requiring external compensation networks. It features a fixed switching frequency of 700 kHz and supports Eco-Mode for improved light-load efficiency. The outputs are adjustable from 760 mV to 7 V. The component is housed in a 16-pin QFN package (RSAR suffix) designed for surface-mount assembly.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific RSAR suffix indicates the reel packaging format when ordering. Confirm that the application circuitry supports the required input voltage range and thermal dissipation for the QFN-16 package. Ensure compatibility with the 700 kHz switching frequency regarding external passive component selection. Check for any recent product change notices affecting pinout or electrical specifications before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when dual isolated rails are required from a single intermediate bus voltage. The 3 A per channel rating suits moderate current loads where space constraints favor integrated solutions over discrete designs. Consider the thermal performance of the exposed pad QFN package for high-duty cycle applications. Verify that the 4.5 V minimum input voltage aligns with the system's lowest operating supply condition.
