TPS54394PWP

Voltage Regulators - DC DC Switching Regulators Overview

The TPS54394PWP is a dual-channel synchronous step-down DC-DC converter 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 output voltage is adjustable from 760 mV to 7 V. Integrated features include a fixed switching frequency of 700 kHz, Eco-Mode technology for light-load efficiency, and D-CAP2 control architecture. The device functions within an ambient temperature range of -40°C to +85°C and is housed in a 16-PowerTSSOP package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Dual-channel synchronous buck topology providing independent adjustable outputs
• Integrated D-CAP2 control architecture for stable operation across varying load conditions
• Eco-Mode technology optimizes efficiency during light-load or standby scenarios
• Built-in protection mechanisms including thermal shutdown and current limiting

Voltage Regulators - DC DC Switching Regulators Applications

• Industrial equipment power distribution systems
• Consumer electronics requiring multi-rail power supplies
• Embedded computing platforms with multiple voltage domains
• Telecommunications infrastructure power management

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix PWP confirms the 16-PowerTSSOP package variant. Confirm RoHS compliance status and moisture sensitivity level requirements against storage and reflow soldering specifications. Ensure the ordering part number matches the exact tape-and-reel or tube packaging configuration required for assembly processes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when dual isolated rails are needed from a single intermediate bus voltage. The 3 A per channel rating supports moderate load applications without external passives. Consider the 700 kHz frequency for balancing component size and efficiency. Verify that the 18 V maximum input aligns with the system supply rail.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the TPS54394 family of dual-channel converters. It shares architectural similarities with the TPS54395 but differs in specific electrical characteristics or pin configurations. The PowerTSSOP package offers a compact footprint suitable for space-constrained printed circuit board designs compared to larger through-hole alternatives.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The TPS54394RSAT and TPS54394PWPR are functionally equivalent variants within the same series. The RSAT uses a QFN-16 package, while the PWPR utilizes the same 16-PowerTSSOP package as the PWP but in reel packaging. Cross-package replacements require schematic and layout modifications.
