Pinout
The LTK5302 is a 6-pin SOT-23 packaged IC, commonly used as a high-efficiency step-down (buck) DC-DC converter. Its pin functions are as follows:
1. VIN: Input voltage (2.5V–5.5V).
2. GND: Ground reference.
3. EN: Enable pin (active high).
4. FB: Feedback pin for output voltage regulation.
5. SW: Switching node (connects to inductor).
6. BST: Bootstrap capacitor connection for high-side MOSFET drive.
It typically delivers up to 2A output current with adjustable or fixed output voltage options. The compact design suits space-constrained applications like portable devices.
