TPS40195RGYTG4

DC DC Switching Controllers Overview

The TPS40195RGYTG4 is a synchronous buck controller from Texas Instruments, designed for high-performance power conversion. It supports an input voltage range of 4.5V to 20V and delivers up to 20A output current. Operating at a fixed switching frequency of 600kHz with a maximum duty cycle of 85%, it features a minimum output voltage of 591mV. The device includes integrated power good monitoring and operates within a temperature range of -40°C to +85°C in a 16-pin HVQCCN package.

DC DC Switching Controllers Feature Summary

• Synchronous buck topology with integrated power good signal
• Voltage-mode control using pulse width modulation
• Supports adjustable operation modes from 1V to 5V

DC DC Switching Controllers Applications

• Point-of-load (POL) converters
• Industrial power supplies
• Telecommunications infrastructure

DC DC Switching Controllers Procurement Notes

Verify the component authenticity by checking the manufacturer's marking code against official datasheets. Ensure the package type matches the specified 16-VQFN (HVQCCN) variant. Confirm RoHS compliance status as indicated in the ordering information. Cross-reference the specific suffix 'G4' to ensure lead-free specifications align with project requirements.

DC DC Switching Controllers Selection Notes

Select this controller when a robust 20A synchronous buck solution is required with a wide input voltage range up to 20V. The fixed 600kHz frequency allows for optimized passive component sizing compared to lower-frequency alternatives. Consider the integrated power good feature if system sequencing or fault detection is critical. Verify that the thermal performance of the QFN package meets the application's heat dissipation needs.

DC DC Switching Controllers Part Context

This component belongs to the TPS4019x family of synchronous buck controllers from Texas Instruments. It shares functional similarities with variants like the TPS40195PWR but differs in package configuration. The RGYT suffix indicates a tape-and-reel packaging format suitable for automated surface-mount assembly processes.

DC DC Switching Controllers Replacement Considerations

The TPS40195RGYR is a compatible alternative within the same series. Ensure pinout compatibility and verify that the non-G4 suffix does not introduce minor specification differences regarding environmental compliance or material composition.
