7Semi 3.3V 2A Mini Buck Converter Breakout Module (Synchronous)

A compact synchronous buck converter that steps a 5–5.5V input down to a stable 3.3V at up to 2A, built on the AP61201 IC for minimal power loss. Its small footprint suits space-constrained boards where every millimetre counts. The synchronous topology keeps heat generation low even under sustained load, which matters in enclosed project boxes with limited airflow.

• Input: 5V–5.5V, Output: 3.3V @ 2A
• AP61201 synchronous buck converter
• High efficiency, low quiescent current
• Miniature breakout form factor

A natural fit for powering 3.3V microcontrollers and sensors from a 5V USB or battery rail — a cleaner, more efficient alternative to a linear regulator in battery-powered or IoT builds.
