TPS64203DBVR

DC DC Switching Controllers Overview

The TPS64203DBVR is an adjustable high-efficiency step-down switching controller manufactured by Texas Instruments. It utilizes a buck topology to provide a single output with a maximum current capacity of 3 A. The device operates at a fixed switching frequency of 800 kHz and supports duty cycles up to 100%. It accepts input voltages ranging from 2.7 V to 6 V and delivers adjustable output voltages between 1.2 V and 6.5 V. Quiescent current is specified at 20 uA. The component functions within an operating temperature range of -40°C to +85°C and is housed in a compact SOT-23-6 surface-mount package.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the required thermal management for the SOT-23-6 package under maximum load conditions. Cross-reference datasheet revisions for any updates to recommended external component values.

DC DC Switching Controllers Selection Notes

Select this controller when a compact solution is required for stepping down input voltages to lower levels with high efficiency. The 800 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 3 A output capability against system peak loads. Evaluate the need for external compensation components based on the specific application stability requirements defined in the technical data.

DC DC Switching Controllers Part Context

This component belongs to the TPS6420x family of step-down controllers from Texas Instruments. It shares functional similarities with models like the TPS64200, though it differs in switching frequency specifications. The family is designed for applications prioritizing size and efficiency in power management circuits.

DC DC Switching Controllers Replacement Considerations

The TPS64203DBVT is a tape-and-reel variant of the same device offering identical electrical characteristics. Verify pinout and thermal performance equivalence before substituting packaging types.
