TPS62175DQCT Synchronous Step-Down Buck Converter (4.75-28V, 500mA, WSON-10)

Power your critical flight electronics directly from your main battery with the TPS62175DQCT synchronous step-down converter. When a standard LDO regulator generates too much heat dropping high voltages, this highly efficient switching converter is the perfect alternative. Capable of handling up to 28V on its input, it is perfectly suited for drawing power straight from multi-cell LiPo batteries (up to 6S) to supply a clean, stable voltage for microcontrollers, GPS modules, and RC radio receivers.

What makes the TPS62175 truly exceptional is its proprietary DCS-Control™ topology, which provides a seamless transition into power-save mode, ensuring incredibly high efficiency even at very light loads. It boasts an ultra-low quiescent current of just 4.8 µA, making it a fantastic choice for always-on drone trackers or standby BMS circuits that cannot afford to drain the battery over time. Delivering up to 500mA of continuous current in a tiny WSON-10 package, it offers a thermally efficient, space-saving solution for custom Battery Eliminator Circuits (BECs) and Power Distribution Boards (PDBs).

Key Features:

• 6S LiPo Compatible: Safely accepts input voltages from 4.75V all the way up to 28V, making it fully compatible with 2S to 6S power systems.

• High Efficiency: Synchronous rectification topology drastically reduces heat generation compared to linear regulators, protecting densely packed PCBs.

• Ultra-Low Quiescent Current: Draws merely 4.8 µA in sleep mode, preserving battery life in always-on or standby applications.

• 500mA Output: Provides plenty of current to reliably power navigation electronics, RF receivers, and sensor arrays simultaneously.
