Description

Description

• SparkFun Buck Regulator Breakout – 3.3V (AP63203)
• Offers a 2 A, synchronous buck converter
• Provides high-efficiency step-down DC or DC conversion
• Fully integrated 125 mΩ high-side power MOSFET
• Supports pulse frequency modulation
• Input voltage range: 3.8 to 32 V

The SparkFun Buck Regulator Breakout – 3.3V (AP63203) is a 2 A, synchronous buck converter with a wide input voltage range of 3.8 to 32 V and fully integrates a 125 mΩ high-side power MOSFET and a 68mΩ low-side power MOSFET to provide high-efficiency step-down DC/DC conversion.

The AP63203 device is easily used by minimizing the external component count due to its adoption of peak current mode control along with its integrated compensation network.
