Diodes Incorporated AP61300Q/AP61302Q Synchronous Buck Converters


Diodes Incorporated AP61300Q/AP61302Q Synchronous Buck Converters are automotive-compliant, 3A, converters having a wide input voltage range of 2.4V to 5.5V. These devices completely integrate a 70mΩ high-side power MOSFET and a 50mΩ low-side power MOSFET which provides high-efficiency step-down DC-DC conversion. The AP61300Q/AP61302Q buck converters can easily be used by minimizing the external component count as it adopts Constant On-Time (COT) control. The COT control helps in achieving fast transient response, easy loop stabilization, and low output voltage ripple. Applications include automotive power systems, automotive infotainment, automotive instrument clusters, automotive telematics, and Advanced Driver Assistance Systems (ADAS).
