Design a Custom BoardSynchronous buck converter regulator supporting adjustable split-rail output for dual supply applications. Delivers up to 4A output current with input voltage range of 4.5V to 17V. Integrated high-side and low-side MOSFETs enable efficient power conversion. Suitable for industrial, automotive, and consumer applications requiring dual voltage rails from single input source.
The 0.5mm pin pitch makes hand soldering impractical without specialized equipment, and the tiny 3x3mm footprint cannot connect directly to breadboards. A breakout board brings these pins to standard 0.1-inch spacing, enabling rapid prototyping of analog-to-digital converters, boost controllers, and audio switches without reflow soldering or custom PCBs.
