3 Description
PL8322 integrates a high efficiency synchronousstep-down switching regulator, which includes a 36V,76mΩ high side and a 36V, 52mΩ low sideMOSFETs to provide 3.1A continuous load currentover 6.5V to 36V wide operating input voltage with33V input over voltage protection. Peak current modecontrol provides fast transient responses andcycle-by-cycle current limiting. PL8322 hasconfigurable line drop compensation, configurablecharging current limit. CC/CV mode control providesa smooth transition between constant currentcharging and constant voltage charging stages.Built-in soft-start prevents inrush current at power-up.
