Get clean, stable power for your embedded systems, IoT devices, and battery-powered projects with the 7Semi DC Buck Converter Breakout. Designed with precision and engineered for performance, this compact breakout board leverages the AP62301 synchronous buck converter to step down voltages efficiently from a wide range of input sources, delivering a steady 3.3V output at a continuous 2A current. Whether you are building a low-noise device, prototyping a PCB, or deploying in a production environment, this power module offers robust protection, high efficiency, and ease of integration.
With support for an input range of 4.2V to 14V, this converter provides the versatility needed for a variety of power scenarios, including USB, Li-ion battery packs, or adapter-based supplies. Its advanced EMI-reduction design, high switching frequency (2.2MHz), and integrated soft-start mechanism make it an optimal choice for noise-sensitive and space-constrained applications. Built-in safety features like over-temperature and over-current protection ensure your components are safeguarded at all times.
Wide Input Voltage Range: Accepts 4.2V to 14V input, compatible with multiple power sources including batteries, adapters, and power rails.
Stable 3.3V Output: Delivers a fixed 3.3V output with up to 2A continuous current—ideal for powering microcontrollers and peripherals.
High Efficiency: Synchronous buck converter topology ensures energy efficiency with minimal heat generation.
Low Output Ripple: Provides a stable voltage with reduced noise, critical for sensitive analog and digital circuits.
EMI Minimisation: Features a proprietary gate driver scheme to reduce high-frequency noise, ensuring cleaner power delivery.
Built-in Protections: Integrated over-temperature and over-current protection for enhanced durability and device safety.
Soft-Start Function: Prevents large inrush currents at startup, reducing stress on connected components.
Compact PCB Footprint: Small board size (18mm x 16mm) ensures easy integration into space-limited designs.
High Switching Frequency: Operates at 2.2MHz, enabling the use of smaller external components for compact system design.
Integrated Compensation: No need for external compensation circuitry, simplifying design and reducing BOM.
