TPS62420DRCTG4

Voltage Regulators - DC DC Switching Regulators Overview

The TPS62420DRCTG4 is a dual synchronous buck DC/DC converter from Texas Instruments, housed in a VSON-10 package. It integrates two independent step-down converters with adjustable output voltages ranging from 600 mV to 6 V. The device supports an input voltage range of 2.5 V to 6 V and delivers up to 1 A total output current, typically split as 600 mA on one channel and 1000 mA on the other. Operating at a fixed switching frequency of 2.25 MHz, it achieves high efficiency while maintaining a low quiescent current of 32 uA. The component functions within a temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the G4 suffix indicates lead-free RoHS compliance and environmental standards. Confirm the DRCT suffix specifies cut-tape packaging rather than reel quantities. Ensure the VSON-10 footprint matches your PCB layout requirements. Cross-reference the specific revision level against your design documentation to guarantee pin compatibility and thermal performance characteristics align with your system constraints.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing systems requiring two isolated regulated outputs from a single input source. It is appropriate for applications where space constraints necessitate a small VSON-10 package. Consider this part if the load profile requires up to 1 A combined current with high efficiency needs. Evaluate the 2.25 MHz frequency against EMI sensitivity requirements in your specific environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the TPS624xx series of dual step-down converters designed for portable applications.
