2) Bootstrap Voltage Regulator: An external 0.1µF ceramic capacitor is required as bootstrap capacitor between BST and SW pins to work as high-side power MOSFET gate driver. 3) Inductor (L): (1) Low DCR for good efficiency (2) Inductance saturate current must higher than the output ...
(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. AP63300 also features Frequency Spread Spectrum (FSS) with a ...
Why it works should be answered by driver experts... and that´s not me. What do you think could happen? Yes, wright... BT and or WiFi does not work correctly. In this case just flash the old one again. If that does not help just shorten the pins 7 and 8 on the board......
