AP61406Q I2C Buck Converters

Diodes Incorporated AP61406Q I2C Buck Converters offer a 2.3V to 5.5V input voltage range and are selectable up to 4A. The synchronous buck converter fully integrates a 75mΩ high-side power MOSFET and a 33mΩ low-side power MOSFET to supply high-efficiency step-down DC/DC conversion. The Diodes Inc AP61406Q is easy to use, minimizing external component count through its constant-on-time (COT) control, which achieves fast transient responses, eases loop stabilization, and reduces output voltage ripple.
