TPS40193DRCT

DC DC Switching Controllers Overview

The TPS40193DRCT is a synchronous buck controller from Texas Instruments designed for high-efficiency power conversion. It operates with an input voltage range of 4.5V to 18V and supports output currents up to 20A. The device features a fixed switching frequency of 300kHz and delivers a regulated output voltage between 591mV and 14.4V. It utilizes voltage-mode control with a maximum duty cycle of 85%. The component functions within an ambient temperature range of -40°C to +85°C and is housed in a compact 10-VSON package.

DC DC Switching Controllers Feature Summary

• Integrated synchronous rectification driver for enhanced efficiency
• Built-in Power Good signal for system monitoring
• Pre-bias startup capability for safe initialization

DC DC Switching Controllers Applications

• Point-of-load (POL) regulation modules
• Telecommunications equipment power distribution
• Industrial control system power supplies

DC DC Switching Controllers Procurement Notes

Verify the specific suffix DRCT indicates cut-tape packaging rather than standard reel quantities. Confirm RoHS compliance status and moisture sensitivity level requirements before integration into manufacturing processes. Ensure the ordering part number matches the exact functional specifications required for the design.

DC DC Switching Controllers Selection Notes

Select this controller when a fixed 300kHz frequency and 20A current capacity are required. It is suitable for designs needing integrated synchronous drive without external MOSFET drivers. Compare against TPS40192 if a higher 600kHz frequency is preferred for smaller passive components.

DC DC Switching Controllers Part Context

This component belongs to the TPS4019x family of synchronous buck controllers. It shares architectural similarities with the TPS40192, differing primarily in switching frequency settings. The series targets single-phase DC-DC conversion applications requiring robust protection features and simple voltage-mode control loops.

DC DC Switching Controllers Replacement Considerations

TPS40192DRCR serves as a functional alternative offering identical pinout and features but operates at a 600kHz switching frequency instead of 300kHz.
