Pinout
The RT3613EEGQW is a 6-pin synchronous step-down DC-DC converter.
Pin Functions:
1. VIN (Pin 1): Power input (4.5V–18V).
2. EN (Pin 2): Enable control (high = on, low = off).
3. FB (Pin 3): Feedback for output voltage regulation.
4. GND (Pin 4): Ground reference.
5. SW (Pin 5): Switching node (connects to inductor).
6. BST (Pin 6): Bootstrap for high-side MOSFET driver.
It provides adjustable output voltage and supports high-efficiency power conversion with integrated MOSFETs.

Package
The RT3613EEGQW is a QFN (Quad Flat No-lead) package. It features a compact, surface-mount design with exposed pads for thermal and electrical performance. Typical dimensions are small (e.g., 3x3mm or similar), with multiple pins on the sides. QFN packages are known for low inductance and efficient heat dissipation, making them suitable for high-frequency or power-sensitive applications.
