TPS62402DRCTG4

Voltage Regulators - DC DC Switching Regulators Overview

The TPS62402DRCTG4 is a dual synchronous step-down DC-DC converter manufactured by Texas Instruments. It integrates two independent buck converters within a compact VSON-EP-10 package measuring 3mm x 3mm. The device supports an input voltage range from 2.5V to 6V. One channel provides a fixed 3.3V output with a maximum current of 600mA, while the second channel offers an adjustable output capability up to 400mA. The integrated switching frequency operates at 2.25MHz. Quiescent current is specified at 32µA during operation and drops to 263µA in standby modes. The component functions reliably across a temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS standards when sourcing. Confirm that the DRCT designation corresponds to cut-tape packaging rather than reel quantities. Ensure the ordering part number matches the exact pinout and thermal pad requirements for your PCB layout. Cross-reference the datasheet revision to confirm feature consistency before finalizing procurement contracts.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when space constraints require a dual-channel solution in a minimal footprint. It is suitable for applications needing one fixed rail and one flexible adjustable rail. Consider the 2.25MHz frequency for balancing efficiency against electromagnetic interference. Evaluate the 400mA and 600mA current limits against peak load requirements to ensure adequate headroom.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the TPS6240x family of dual step-down converters designed for low-power applications. It shares architectural similarities with the TPS62400 and TPS62403 but differs in output configuration options. The series emphasizes high efficiency and small form factors for modern portable electronics. It serves as a direct alternative to single-channel regulators where multiple voltages are required.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The TPS62402DRCR is a functional equivalent with identical electrical specifications. Verify if the G4 suffix strictly denotes environmental compliance without altering pin compatibility. Check for availability of the standard DRCT variant if the G4 version is discontinued.
