TPS64201DBVR

DC DC Switching Controllers Overview

The TPS64201DBVR is a high-efficiency step-down switching controller manufactured by Texas Instruments. It operates with a fixed switching frequency of 450 kHz and supports an input voltage range from 1.8 V to 6.5 V. The device delivers up to 3 A output current with adjustable output voltages ranging from 1.2 V to 6.5 V. It features a low quiescent current of 20 µA and achieves a maximum duty cycle of 100%. The component is housed in a compact SOT-23-6 package and functions within a temperature range of -40°C to +85°C.

DC DC Switching Controllers Feature Summary

• High efficiency operation enabled by a fixed 450 kHz switching frequency
• Supports 100% duty cycle for minimal dropout voltage requirements
• Ultra-low standby power consumption with 20 µA operating supply current

DC DC Switching Controllers Applications

• Portable battery-powered consumer electronics
• Industrial control systems requiring efficient DC-DC conversion
• Embedded systems with strict power budget constraints

DC DC Switching Controllers Procurement Notes

Verify the specific ordering suffix 'R' corresponds to the reel packaging configuration as indicated in distributor catalogs. Confirm that the SOT-23-6 footprint matches the target PCB layout dimensions. Ensure the application environment remains within the specified -40°C to +85°C operating temperature range for reliable performance. Cross-reference the manufacturer part number with official datasheets to validate electrical characteristics before integration.

DC DC Switching Controllers Selection Notes

Select this component when designing space-constrained applications requiring a buck topology with high efficiency at moderate currents. The fixed 450 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 3 A current limit and 100% duty cycle capability for inputs close to the desired output voltage. Evaluate thermal management requirements given the small SOT-23-6 package size under full load conditions.
