Diodes Included AP64200Q Automotive Synchronous Buck Converter

Diodes Included AP64200Q Automotive Synchronous Buck Converter totally integrates a 150mΩ high-side energy MOSFET and an 80mΩ low-side energy MOSFET to offer high-efficiency step-down DC-DC conversion. The AP64200Q design is optimized for Electromagnetic Interference (EMI) discount.

The Diodes Included AP64200Q Converter is well utilized by minimizing the exterior part depend as a consequence of its peak present mode management adoption. The system has a proprietary gate driver scheme to withstand switching node ringing with out sacrificing MOSFET turn-on and turn-off instances, which reduces high-frequency radiated EMI noise attributable to MOSFET switching. Moreover, the AP64200Q additionally options Frequency Unfold Spectrum (FSS) with a switching frequency jitter of ±6%, which reduces EMI by not permitting emitted power to remain in anybody frequency for a big time frame.

The AP64200Q is offered in a SO-8EP bundle with a 3.8V to 40V enter voltage vary.
