Diodes Incorporated AP64202 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. In addition, the Diodes Inc AP64202 Synchronous Buck Converter minimizes external component count with a peak current mode control and its integrated loop compensation network.
The AP64202 Converter design is optimized for Electromagnetic Interference (EMI) reduction. 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. The AP64202 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 time.
The device is housed in a SO-8EP (Standard) package with a wide input voltage range of 3.8V to 40V.
