Pinout
The SY8113BADC is a 6-pin synchronous buck converter IC with the following pin functions:
1. VIN (Pin 1) – Input voltage (2.5V–5.5V).
2. GND (Pin 2) – Ground reference.
3. EN (Pin 3) – Enable control (high = on, low = off).
4. SW (Pin 4) – Switching node (connects to inductor).
5. FB (Pin 5) – Feedback for output voltage regulation.
6. PG (Pin 6) – Power Good indicator (open-drain output).
It provides up to 3A output current with high efficiency and integrates power MOSFETs. The PG pin signals when the output is within regulation.
