Dual 400 mA / 600 mA buck with 2.25 MHz switching
The TPS62402DRCT is a dual-channel step-down (buck) converter from Texas Instruments, delivering 400 mA on one output and 600 mA on the other, with a 2.25 MHz switching frequency that allows small external inductors and capacitors — a typical BOM saving for space-constrained designs like portable instrumentation or wireless modules.
Input range and output programmability
The input voltage range runs from 2.5 V to 6 V, covering single-cell Li-Ion and 3.3 V / 5 V rails. The output is programmable: the fixed options are 1.2 V, 1.8 V, or 3.3 V, selected by pin-strapping — no external resistor divider needed for the fixed versions.
Temperature grade and package reality
The package is a 10-VFDFN with exposed pad, supplied as 10-VSON (3x3 mm).
Sourcing posture and lifecycle status
Texas Instruments continues to manufacture this part, and it is available through authorized distribution channels. The base product number is TPS62402, so any future PCN or EOL notification would reference that family.
