TPS62177DQCT

Voltage Regulators - DC DC Switching Regulators Overview

The TPS62177DQCT is a synchronous step-down DC-DC converter from Texas Instruments, featuring DCS-Control topology. It operates with an input voltage range of 4.75V to 28V and provides a fixed 3.3V output at up to 500mA. The device integrates a 1MHz switching frequency and includes SNOOZ mode for enhanced efficiency in light-load conditions. Packaged in a compact 10-WSON (3x2) format, it supports surface-mount installation.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates DCS-Control technology for stable operation across varying load and line conditions without external compensation components.
• Features SNOOZ mode architecture to significantly reduce quiescent current during low-power or standby operational states.
• Utilizes synchronous rectification to maximize conversion efficiency and minimize power loss within the integrated circuit.

Voltage Regulators - DC DC Switching Regulators Applications

• Portable battery-powered consumer electronics requiring efficient voltage regulation
• Industrial control systems utilizing single-supply architectures
• Embedded computing modules needing compact power management solutions

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'DGSR' or 'DQCR' against datasheet documentation, as 'DQCT' may indicate a specific tape-and-reel configuration or distributor-specific designation. Confirm RoHS compliance status and ensure the package matches the required PCB footprint. Cross-reference ordering part numbers with official Texas Instruments channels to avoid counterfeit components.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when input voltages exceed standard 5V rails but remain below 28V. The fixed 3.3V output eliminates external feedback resistor networks. Consider the thermal performance of the WSON package for high-density layouts. Ensure the application does not require adjustable output voltages, which would necessitate alternative model variants.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the TPS6217x family of DCS-Control buck converters. It shares architectural similarities with the TPS62175 and TPS62176 but is distinguished by its higher maximum input voltage rating of 28V. The series emphasizes small solution size and high efficiency for space-constrained portable applications.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include TPS62175DQCT and TPS62176DQCT, though input voltage ranges differ. Verify pin compatibility and thermal characteristics before substitution. Alternative families like TPS6213x offer similar functionality with different current ratings.
