The SY8029AIC is a 6-pin synchronous buck converter IC with the following pin functions:
1. EN (Pin 1) – Enable control (high = on, low = off).
2. VIN (Pin 2) – Input voltage supply (2.5V–5.5V).
3. SW (Pin 3) – Switching node (connects to inductor).
4. GND (Pin 4) – Ground reference.
5. FB (Pin 5) – Feedback for output voltage regulation.
6. PG (Pin 6) – Power Good indicator (open-drain output).
It provides efficient step-down DC-DC conversion with up to 2A output current and adjustable output voltage. The PG pin signals when the output is within regulation.
