AP63205WU Synchronous Step-Down Buck Converter (3.8V-32V to 5V, 2A)

Provide rock-solid 5V power to your flight controllers, receivers, and sensitive electronics with the AP63205WU synchronous step-down converter. Designed to deliver a fixed 5V output without the need for external voltage divider resistors, this IC greatly simplifies your custom PCB layouts and reduces the overall component count for DIY BEC (Battery Eliminator Circuit) modules.

With a massive input voltage range of 3.8V to 32V, it effortlessly handles power directly from 2S up to 7S LiPo battery packs. Its synchronous rectification technology ensures outstanding power efficiency, allowing it to deliver up to 2A of continuous output current while minimizing heat generation. Housed in a low-profile TSOT26 package, it is the perfect space-saving power solution for compact FPV drones, RC models, and industrial IoT devices requiring a highly reliable 5V rail.

Key Features:

• Fixed 5V Output: Eliminates the need for external feedback resistors, guaranteeing a perfectly stable 5V supply for microcontrollers and logic circuits.

• Wide Input Range: Safely accepts input voltages from 3.8V all the way up to 32V, making it fully compatible with multi-cell LiPo setups (up to 7S).

• High Efficiency: Synchronous step-down topology minimizes power loss and prevents excessive overheating on densely packed circuit boards.

• 2A Current Capacity: Delivers plenty of continuous current to power power-hungry RF modules, GPS units, and multiple sensors simultaneously.
