AP63356QZV-7

The AP63356Q/AP63357Q is an automotive-compliant, 3.5A, synchronous buck converter with a wide input voltage range of 3.8V to 32V. The device fully integrates a 74mΩ high-side power MOSFET and a 40mΩ low-side power MOSFET to provide high-efficiency stepdown DC-DC conversion. The AP63356Q/AP63357Q device is easily used by minimizing the external component count due to its adoption of peak current mode control along with its integrated loop compensation network. The AP63356Q/AP63357Q 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. AP63356Q/AP63357Q 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 device is available in a 3mm × 2mm, V-DFN3020-13/SWP (Type A1), package with wettable flanks.
