CS5080E PCB note
(1) the power line should be as wide as possible, should be separate from the power line is CS5080E power supply.
(2) the BOOST module main current loop line should be short and thick
(3) the LX walk line is short, as far as possible to reduce EMI
(4) should be directly connected inductance and schottky, wired short and thick, avoid via jump line.
(5) the power supply side as near to the chip capacitors should be placed in the
(6) chip at the bottom of the heat sink is power, should be in the vast land is linked together, at the bottom of the heat sink must and reliable welding.
