TPS54202HDDCR

Voltage Regulators - DC DC Switching Regulators Overview

The TPS54202HDDCR is a synchronous step-down voltage converter from Texas Instruments, operating within a 4.5 V to 28 V input range and delivering up to 2 A of output current. It utilizes a fixed 500 kHz switching frequency and features an SOT-23-THIN-6 package. The device includes integrated high-side (148 mΩ) and low-side (78 mΩ) MOSFETs, internal loop compensation, and a 5 ms soft-start timer. Quiescent current is specified at 45 μA, with shutdown current as low as 2 μA. It supports Eco-mode for light-load efficiency and operates across a junction temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'H' against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications, as variations may exist within the family. Ensure the ordering part number matches the required tape-and-reel quantity or cut-tape availability. Cross-reference the RoHS status and assembly site information provided in the latest product change notices to ensure compliance with project requirements.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is required for medium-power applications due to its small SOT-23 footprint. It is suitable for designs needing wide input voltage tolerance and efficient light-load operation. Consider the fixed 500 kHz frequency for balancing component size and efficiency. Verify that the 2 A continuous current rating meets the maximum load demand under all expected operating temperatures.
