Diodes Incorporated AP64200Q Automotive Synchronous Buck Converter fully integrates a 150mΩ high-side power MOSFET and an 80mΩ low-side power MOSFET to provide high-efficiency step-down DC-DC conversion. The AP64200Q design is optimized for Electromagnetic Interference (EMI) reduction. Available at Mouser. the Diodes Incorporated AP64200Q Converter is easily used by minimizing the external component count due to its peak current mode control adoption. The device has a proprietary gate driver scheme to resist switching node ringing without sacrificing MOSFET turn-on and turn-off times, which reduces high-frequency radiated EMI noise caused by MOSFET switching. Additionally, the AP64200Q also features Frequency Spread Spectrum (FSS) with a switching frequency jitter of ±6%, which reduces EMI by not allowing emitted energy to stay in any one frequency for a significant period of time. The AP64200Q is available in a SO-8EP package with a 3.8V to 40V input voltage range.
